NAME
       xterm - terminal emulator for X

SYNOPSIS
       xterm [-toolkitoption ...] [-option ...] [shell]

DESCRIPTION
       The  xterm  program is a terminal emulator for the X Window System.  It
       provides DEC VT102/VT220 (VTxxx) and Tektronix 4014  compatible	termi-
       nals  for  programs that cannot use the window system directly.	If the
       underlying operating system  supports  terminal	resizing  capabilities
       (for  example,  the  SIGWINCH  signal  in systems derived from 4.3bsd),
       xterm will use the facilities to notify programs running in the	window
       whenever it is resized.

       The  VTxxx  and	Tektronix 4014 terminals each have their own window so
       that you can edit text in one and look at graphics in the other at  the
       same  time.   To maintain the correct aspect ratio (height/width), Tek-
       tronix graphics will be restricted to the largest  box  with  a	4014's
       aspect  ratio  that will fit in the window.  This box is located in the
       upper left area of the window.

       Although both windows may be displayed at the same time, one of them is
       considered  the ''active'' window for receiving keyboard input and ter-
       minal output.  This is the window that contains the text	 cursor.   The
       active  window  can  be	chosen	through	 escape	 sequences,  the  ''VT
       Options'' menu in the VTxxx window, and the ''Tek Options'' menu in the
       4014 window.

EMULATIONS
       The  VT102  emulation  is fairly complete, but does not support autore-
       peat.  Double-size characters  are  displayed  properly	if  your  font
       server  supports	 scalable fonts.  The VT220 emulation does not support
       soft fonts, it is otherwise complete.   Termcap(5)  entries  that  work
       with  xterm  include  an	 optional  platform-specific entry, ''xterm,''
       ''vt102,'' ''vt100'' and ''ansi,'' and ''dumb.''	  xterm	 automatically
       searches the termcap file in this order for these entries and then sets
       the ''TERM'' and the ''TERMCAP'' environment variables.	You  may  also
       use  ''vt220,''	 but  must  set	 the terminal emulation level with the
       decTerminalID resource.	(The ''TERMCAP'' environment variable  is  not
       set  if xterm is linked against a terminfo library, since the requisite
       information is not  provided  by	 the  termcap  emulation  of  terminfo
       libraries).

       Many  of	 the special xterm features may be modified under program con-
       trol through a set of escape  sequences	different  from	 the  standard
       VT102 escape sequences.	(See the Xterm Control Sequences document.)

       The  Tektronix  4014 emulation is also fairly good.  It supports 12-bit
       graphics addressing, scaled to the window size.	 Four  different  font
       sizes and five different lines types are supported.  There is no write-
       through or defocused mode support.  The	Tektronix  text	 and  graphics
       commands	 are recorded internally by xterm and may be written to a file
       by sending the COPY escape sequence (or through the Tektronix menu; see
       below).	 The  name  of	the  file will be ''COPYyyyy-MM-dd.hh:mm:ss'',
       where yyyy, MM, dd, hh, mm and ss  are  the  year,  month,  day,	 hour,
       minute  and  second when the COPY was performed (the file is created in
       the directory xterm is started in, or the home directory	 for  a	 login
       xterm).

       Not all of the features described in this manual are necessarily avail-
       able in this version of xterm.  Some (e.g., the	non-VT220  extensions)
       are  available only if they were compiled in, though the most commonly-
       used are in the default configuration.

OTHER FEATURES
       Xterm automatically highlights the text cursor when the pointer	enters
       the  window  (selected) and unhighlights it when the pointer leaves the
       window (unselected).  If the window is the focus window, then the  text
       cursor is highlighted no matter where the pointer is.

       In VT102 mode, there are escape sequences to activate and deactivate an
       alternate screen buffer, which is the same size as the display area  of
       the  window.   When activated, the current screen is saved and replaced
       with the alternate screen.  Saving of lines scrolled off the top of the
       window is disabled until the normal screen is restored.	The termcap(5)
       entry for xterm allows the visual editor vi(1) to switch to the	alter-
       nate  screen  for  editing  and to restore the screen on exit.  A popup
       menu entry makes it simple to switch between the normal	and  alternate
       screens for cut and paste.

       In either VT102 or Tektronix mode, there are escape sequences to change
       the name of the windows.	 Additionally, in VT102 mode, xterm implements
       the window-manipulation control sequences from dtterm, such as resizing
       the window, setting its location on the screen.

       Xterm allows character-based applications to receive mouse events (cur-
       rently  button-press  and  release events, and button-motion events) as
       keyboard control sequences.  See Xterm Control Sequences for details.

OPTIONS
       The xterm terminal emulator accepts the standard X Toolkit command line
       options	as  well  as many application-specific options.	 If the option
       begins with a '+' instead of a '-',  the	 option	 is  restored  to  its
       default	value.	The -version and -help options are interpreted even if
       xterm cannot open the display, and are useful for testing and  configu-
       ration scripts:

       -version
	       This  causes  xterm  to	print a version number to the standard
	       output.

       -help   This causes xterm to print out a verbose message describing its
	       options,	 one per line.	The message is written to the standard
	       output.	Xterm generates this message, sorting  it  and	noting
	       whether a "-option" or a "+option" turns the feature on or off,
	       since some features historically have been one  or  the	other.
	       Xterm  generates	 a  concise help message (multiple options per
	       line) when an unknown option is used, e.g.,
		    xterm -z

	       If the logic for a particular option such  as  logging  is  not
	       compiled	 into xterm, the help text for that option also is not
	       displayed by the -help option.

       One parameter (after all options) may be given.	That overrides xterm's
       built-in	 choice	 of  shell  program.   Normally xterm checks the SHELL
       variable.  If that is not set, xterm tries to  use  the	shell  program
       specified  in  the  password  file.   If	 that  is  not set, xterm uses
       /bin/sh.	 If the parameter names an executable file,  xterm  uses  that
       instead.	  The parameter must be an absolute path, or name a file found
       on the user's PATH (and thereby construct an absolute  path).   The  -e
       option  cannot be used with this parameter since it uses all parameters
       following the option.

       The other options are used to control the appearance and behavior.  Not
       all options are necessarily configured into your copy of xterm:

       -132    Normally,  the  VT102  DECCOLM  escape  sequence	 that switches
	       between 80 and 132 column mode is ignored.  This option	causes
	       the  DECCOLM  escape  sequence  to be recognized, and the xterm
	       window will resize appropriately.

       -ah     This option indicates that xterm should	always	highlight  the
	       text cursor.  By default, xterm will display a hollow text cur-
	       sor whenever the focus is lost or the pointer leaves  the  win-
	       dow.

       +ah     This  option  indicates	that xterm should do text cursor high-
	       lighting based on focus.

       -ai     This option disables active icon support if  that  feature  was
	       compiled	 into  xterm.  This is equivalent to setting the vt100
	       resource activeIcon to ''false''.

       +ai     This option enables active icon support	if  that  feature  was
	       compiled	 into  xterm.  This is equivalent to setting the vt100
	       resource activeIcon to ''true''.

       -aw     This option indicates that auto-wraparound should  be  allowed.
	       This  allows  the cursor to automatically wrap to the beginning
	       of the next line when when it is at the rightmost position of a
	       line and text is output.

       +aw     This  option  indicates	that  auto-wraparound  should  not  be
	       allowed.

       -b number
	       This option specifies the size of the inner  border  (the  dis-
	       tance  between  the outer edge of the characters and the window
	       border) in pixels.  That is the vt100 internalBorder  resource.
	       The default is 2.

       +bc     turn  off text cursor blinking.	This overrides the cursorBlink
	       resource.

       -bc     turn on text cursor blinking.  This overrides  the  cursorBlink
	       resource.

       -bcf milliseconds
	       set the amount of time text cursor is off when blinking via the
	       cursorOffTime resource.

       -bcn milliseconds
	       set the amount of time text cursor is on when blinking via  the
	       cursorOffTime resource.

       -bdc    Set  the vt100 resource colorBDMode to ''false'', disabling the
	       display of characters with bold attribute as color

       +bdc    Set the vt100 resource colorBDMode to  ''true'',	 enabling  the
	       display	of characters with bold attribute as color rather than
	       bold

       -cb     Set the vt100 resource cutToBeginningOfLine to ''false''.

       +cb     Set the vt100 resource cutToBeginningOfLine to ''true''.

       -cc characterclassrange:value[,...]
	       This sets classes indicated by the given ranges	for  using  in
	       selecting  by  words.   See  the	 section  specifying character
	       classes.	 and discussion of the charClass resource.

       -cjk_width
	       Set the cjkWidth resource to ''true''.  When turned on, charac-
	       ters  with  East	 Asian Ambiguous (A) category in UTR 11 have a
	       column width of 2.  Otherwise, they have a column width	of  1.
	       This may be useful for some legacy CJK text terminal-based pro-
	       grams assuming box drawings and others to have a	 column	 width
	       of  2.  It also has to be turned on when you specify a TrueType
	       CJK double-width (bi-width/monospace) font either with  -fa  at
	       the   command  line  or	faceName  resource.   The  default  is
	       ''false''

       +cjk_width
	       Reset the cjkWidth resource.

       -class string
	       This option allows you  to  override  xterm's  resource	class.
	       Normally	 it is ''XTerm'', but can be set to another class such
	       as ''UXTerm'' to override selected resources.

       -cm     This option disables recognition of  ANSI  color-change	escape
	       sequences.  It sets the colorMode resource to ''false''.

       +cm     This  option  enables  recognition  of ANSI color-change escape
	       sequences.  This is the same as the vt100 resource colorMode.

       -cn     This option indicates that newlines should not be cut in	 line-
	       mode selections.	 It sets the cutNewline resource to ''false''.

       +cn     This option indicates that newlines should be cut in  line-mode
	       selections.  It sets the cutNewline resource to ''true''.

       -cr color
	       This  option  specifies	the color to use for text cursor.  The
	       default is to use the same foreground color that	 is  used  for
	       text.  It sets the cursorColor resource according to the param-
	       eter.

       -cu     This option indicates that xterm should work around  a  bug  in
	       the more(1) program that causes it to incorrectly display lines
	       that are exactly the width of the window and are followed by  a
	       line beginning with a tab (the leading tabs are not displayed).
	       This option is so named because it was originally thought to be
	       a bug in the curses(3x) cursor motion package.

       +cu     This  option  indicates	that  xterm should not work around the
	       more(1) bug mentioned above.

       -dc     This option disables the escape sequence to change dynamic col-
	       ors:  the vt100 foreground and background colors, its text cur-
	       sor color, the pointer cursor foreground and background colors,
	       the  Tektronix  emulator	 foreground and background colors, its
	       text cursor color and highlight color.	The  option  sets  the
	       dynamicColors option to ''false''.

       +dc     This  option enables the escape sequence to change dynamic col-
	       ors.  The option sets the dynamicColors option to ''true''.

       -e program [ arguments ... ]
	       This option specifies the program (and its command  line	 argu-
	       ments)  to be run in the xterm window.  It also sets the window
	       title and icon name to be the basename  of  the	program	 being
	       executed	 if  neither  -T nor -n are given on the command line.
	       This must be the last option on the command line.

       -en encoding
	       This option determines the encoding on which  xterm  runs.   It
	       sets  the locale resource.  Encodings other than UTF-8 are sup-
	       ported by using luit.  The -lc option should be used instead of
	       -en for systems with locale support.

       -fb font
	       This  option  specifies	a font to be used when displaying bold
	       text.  This font must be the  same  height  and	width  as  the
	       normal font.  If only one of the normal or bold fonts is speci-
	       fied, it will be used as the normal font and the bold font will
	       be  produced  by	 overstriking this font.  The default is to do
	       overstriking of the normal font.	 See also  the	discussion  of
	       boldFont and boldMode resources.

       -fa pattern
	       This  option  sets  the	pattern	 for  fonts  selected from the
	       FreeType library if support for that library was compiled  into
	       xterm.	This corresponds to the faceName resource.  When a CJK
	       double-width font is specified, you also need to	 turn  on  the
	       cjkWidth resource.

       -fbb    This option indicates that xterm should compare normal and bold
	       fonts bounding boxes to ensure they are	compatible.   It  sets
	       the freeBoldBox resource to ''false''.

       +fbb    This  option indicates that xterm should not compare normal and
	       bold fonts bounding boxes to ensure they	 are  compatible.   It
	       sets the freeBoldBox resource to ''true''.

       -fbx    This  option  indicates	that  xterm should not assume that the
	       normal and bold fonts have VT100 line-drawing  characters.   If
	       any  are	 missing, xterm will draw the characters directly.  It
	       sets the forceBoxChars resource to ''false''.

       +fbx    This option indicates that xterm should assume that the	normal
	       and bold fonts have VT100 line-drawing characters.  It sets the
	       forceBoxChars resource to ''true''.

       -fd pattern
	       This option sets the pattern for	 double-width  fonts  selected
	       from  the FreeType library if support for that library was com-
	       piled into xterm.  This corresponds to  the  faceNameDoublesize
	       resource.

       -fi font
	       This  option sets the font for active icons if that feature was
	       compiled into xterm.  See also the discussion of	 the  iconFont
	       resource.

       -fs size
	       This  option  sets  the	pointsize  for fonts selected from the
	       FreeType library if support for that library was compiled  into
	       xterm.  This corresponds to the faceSize resource.

       -fw font
	       This  option  specifies the font to be used for displaying wide
	       text.  By default, it will attempt to use a font twice as  wide
	       as  the font that will be used to draw normal text.  If no dou-
	       blewidth font is found, it will improvise,  by  stretching  the
	       normal font.  This corresponds to the wideFont resource.

       -fwb font
	       This  option  specifies the font to be used for displaying bold
	       wide text.  By default, it will attempt to use a font twice  as
	       wide  as	 the  font that will be used to draw bold text.	 If no
	       doublewidth font is found, it will improvise, by stretching the
	       bold font.  This corresponds to the wideBoldFont resource.

       -fx font
	       This  option  specifies	the font to be used for displaying the
	       preedit string in the "OverTheSpot" input method.  See also the
	       discussion of the ximFont resource.

       -hc color
	       This  option  specifies	the color to use for the background of
	       selected or otherwise  highlighted  text.   If  not  specified,
	       reverse	video  is  used.  See the discussion of the highlight-
	       Color resource.

       -hf     This option indicates that HP Function Key escape codes	should
	       be  generated  for  function  keys.  It sets the hpFunctionKeys
	       resource to ''true''.

       +hf     This option indicates that HP Function Key escape codes	should
	       not be generated for function keys.  It sets the hpFunctionKeys
	       resource to ''false''.

       -hold   Turn on the hold resource, i.e.,	 xterm	will  not  immediately
	       destroy	its  window when the shell command completes.  It will
	       wait until you use the window manager to destroy/kill the  win-
	       dow,  or	 if you use the menu entries that send a signal, e.g.,
	       HUP or KILL.

       +hold   Turn off	 the  hold  resource,  i.e.,  xterm  will  immediately
	       destroy its window when the shell command completes.

       -ie     Turn on the ptyInitialErase resource, i.e., use the pseudo-ter-
	       minal's sense of the stty erase value.

       +ie     Turn off the ptyInitialErase resource, i.e., set the stty erase
	       value  using  the  kb string from the termcap entry as a refer-
	       ence, if available.

       -im     Turn on the useInsertMode resource, which forces use of	insert
	       mode  by	 adding appropriate entries to the TERMCAP environment
	       variable.

       +im     Turn off the useInsertMode resource.

       -into windowId
	       Given an X window identifier (a decimal	integer),  xterm  will
	       reparent	 its  top-level	 shell widget to that window.  This is
	       used to embed xterm within other applications.

       -j      This option indicates that xterm should do jump scrolling.   It
	       corresponds  to	the  jumpScroll	 resource.   Normally, text is
	       scrolled one line at a time; this option allows xterm  to  move
	       multiple	 lines	at  a  time  so	 that  it does not fall as far
	       behind.	Its use is strongly recommended since it  makes	 xterm
	       much  faster  when scanning through large amounts of text.  The
	       VT100 escape sequences for enabling and disabling smooth scroll
	       as  well	 as  the  ''VT Options'' menu can be used to turn this
	       feature on or off.

       +j      This option indicates that xterm should not do jump  scrolling.

       -k8     This   option   sets   the   allowC1Printable  resource.	  When
	       allowC1Printable is set, xterm overrides the mapping of C1 con-
	       trol characters (code 128-159) to treat them as printable.

       +k8     This option resets the allowC1Printable resource.

       -kt keyboardtype
	       This  option  sets  the keyboardType resource.  Possible values
	       include: ''unknown'', ''default'', ''hp'', ''sco'', ''sun'' and
	       ''vt220''.

	       The  value ''unknown'', causes the corresponding resource to be
	       ignored.

	       The value  ''default'',	suppresses  the	 associated  resources
	       hpFunctionKeys,	scoFunctionKeys,  sunFunctionKeys  and sunKey-
	       board, using the Sun/PC keyboard layout.

       -l      Turn logging on.	 Normally logging is  not  supported,  due  to
	       security	 concerns.   Some  versions  of xterm may have logging
	       enabled.	 The logfile is written to the	directory  from	 which
	       xterm is invoked.  The filename is generated, of the form

		    XtermLog.XXXXXX

	       or

		    Xterm.log.hostname.yyyy.mm.dd.hh.mm.ss.XXXXXX

	       depending on how xterm was built.

       +l      Turn logging off.

       -lc     Turn  on	 support  of various encodings according to the users'
	       locale setting, i.e., LC_ALL,  LC_CTYPE,	 or  LANG  environment
	       variables.   This  is  achieved by turning on UTF-8 mode and by
	       invoking luit  for  conversion  between	locale	encodings  and
	       UTF-8.	(luit  is  not invoked in UTF-8 locales.)  This corre-
	       sponds to the locale resource.

	       The actual list of encodings which are supported is  determined
	       by  luit.   Consult  the	 luit manual page for further details.
	       See also the discussion of the -u8 option which supports	 UTF-8
	       locales.

       +lc     Turn  off  support  of automatic selection of locale encodings.
	       Conventional 8bit mode or, in UTF-8 locales or with -u8 option,
	       UTF-8 mode will be used.

       -lcc path
	       File  name  for the encoding converter from/to locale encodings
	       and UTF-8 which is used with -lc	 option	 or  locale  resource.
	       This corresponds to the localeFilter resource.

       -leftbar
	       Force  scrollbar to the left side of VT100 screen.  This is the
	       default, unless you have set the rightScrollBar resource.

       -lf filename
	       Specify the log-filename.  See the -l option.

       -ls     This option indicates that the shell that  is  started  in  the
	       xterm  window  will be a login shell (i.e., the first character
	       of argv[0] will be a dash, indicating  to  the  shell  that  it
	       should read the user's .login or .profile).

	       The  -ls	 flag and the loginShell resource are ignored if -e is
	       also given, because xterm does not know how to make  the	 shell
	       start  the  given  command  after whatever it does when it is a
	       login shell - the user's shell of choice need not be  a	Bourne
	       shell  after all.  Also, xterm -e is supposed to provide a con-
	       sistent functionality for other applications that need to start
	       text-mode  programs  in	a  window,  and if loginShell were not
	       ignored, the result of ~/.profile might interfere with that.

	       If you do want the effect of -ls and -e simultaneously, you may
	       get away with something like
		      xterm -e /bin/bash -l -c "my command here"

	       Finally,	 -ls  is  not completely ignored, because xterm -ls -e
	       does write a /etc/wtmp entry (if configured to do so),  whereas
	       xterm -e does not.

       +ls     This option indicates that the shell that is started should not
	       be a login shell (i.e., it will be a normal ''subshell'').

       -mb     This option indicates that xterm should ring a margin bell when
	       the  user  types near the right end of a line.  This option can
	       be turned on and off from the ''VT Options'' menu.

       +mb     This option indicates that margin bell should not be rung.

       -mc milliseconds
	       This option specifies  the  maximum  time  between  multi-click
	       selections.

       -mesg   Turn  off the messages resource, i.e., disallow write access to
	       the terminal.

       +mesg   Turn on the messages resource, i.e., allow write access to  the
	       terminal.

       -mk_width
	       Set  the	 mkWidth resource to ''true''.	This makes xterm use a
	       built-in version of the wide-character width calculation.   The
	       default is ''false''

       +mk_width
	       Reset the mkWidth resource.

       -ms color
	       This option specifies the color to be used for the pointer cur-
	       sor.  The default is to use the foreground  color.   This  sets
	       the pointerColor resource.

       -nb number
	       This  option  specifies the number of characters from the right
	       end of a line at which the margin bell, if enabled, will	 ring.
	       The default is 10.

       -nul    This option disables the display of underlining.

       +nul    This option enables the display of underlining.

       -pc     This  option enables the PC-style use of bold colors (see bold-
	       Colors resource).

       +pc     This option disables the PC-style use of bold colors.

       -pob    This option indicates that the window should be raised whenever
	       a Control-G is received.

       +pob    This  option  indicates	that  the  window should not be raised
	       whenever a Control-G is received.

       -rightbar
	       Force scrollbar to the right side of VT100 screen.

       -rvc    This option disables the display	 of  characters	 with  reverse
	       attribute as color.

       +rvc    This  option  enables  the  display  of characters with reverse
	       attribute as color.

       -rw     This  option  indicates	that  reverse-wraparound   should   be
	       allowed.	  This	allows the cursor to back up from the leftmost
	       column of one line to the  rightmost  column  of	 the  previous
	       line.  This is very useful for editing long shell command lines
	       and is encouraged.  This option can be turned on and  off  from
	       the ''VT Options'' menu.

       +rw     This  option  indicates	that  reverse-wraparound should not be
	       allowed.

       -s      This option indicates that  xterm  may  scroll  asynchronously,
	       meaning	that the screen does not have to be kept completely up
	       to date while scrolling.	 This allows xterm to run faster  when
	       network	latencies  are	very high and is typically useful when
	       running across a very large internet or many gateways.

       +s      This option indicates that xterm should scroll synchronously.

       -samename
	       Does not send title and icon  name  change  requests  when  the
	       request	would  have  no effect: the name is not changed.  This
	       has the advantage of preventing flicker and the disadvantage of
	       requiring  an  extra  round  trip to the server to find out the
	       previous value.	In practice this should never be a problem.

       +samename
	       Always send title and icon name change requests.

       -sb     This option indicates  that  some  number  of  lines  that  are
	       scrolled	 off  the top of the window should be saved and that a
	       scrollbar should be  displayed  so  that	 those	lines  can  be
	       viewed.	 This  option  may  be turned on and off from the ''VT
	       Options'' menu.

       +sb     This option indicates that a scrollbar should not be displayed.

       -sf     This option indicates that Sun Function Key escape codes should
	       be generated for function keys.

       +sf     This option indicates that the standard escape codes should  be
	       generated for function keys.

       -si     This  option indicates that output to a window should not auto-
	       matically reposition the screen to the bottom of the  scrolling
	       region.	 This  option  can  be turned on and off from the ''VT
	       Options'' menu.

       +si     This option indicates that output to a window should  cause  it
	       to scroll to the bottom.

       -sk     This  option  indicates	that  pressing	a  key while using the
	       scrollbar to review previous lines of  text  should  cause  the
	       window  to be repositioned automatically in the normal position
	       at the bottom of the scroll region.

       +sk     This option indicates that  pressing  a	key  while  using  the
	       scrollbar should not cause the window to be repositioned.

       -sl number
	       This  option  specifies	the  number of lines to save that have
	       been scrolled off the top of the screen.	 This  corresponds  to
	       the saveLines resource.	The default is 64.

       -sm     This  option,  corresponding  to the sessionMgt resource, indi-
	       cates that xterm should set up session manager callbacks.

       +sm     This option indicates that xterm should not set up session man-
	       ager callbacks.

       -sp     This  option  indicates that Sun/PC keyboard should be assumed,
	       providing mapping for keypad '+' to ',', and  CTRL-F1  to  F13,
	       CTRL-F2 to F14, etc.

       +sp     This  option indicates that the standard escape codes should be
	       generated for keypad and function keys.

       -t      This option indicates that  xterm  should  start	 in  Tektronix
	       mode,  rather  than  in	VT102 mode.  Switching between the two
	       windows	is  done  using	 the  ''Options''  menus.   Termcap(5)
	       entries	 that	work   with  xterm  ''tek4014,''  ''tek4015,''
	       ''tek4012'', ''tek4013'' and ''tek4010,'' and ''dumb.''	 xterm
	       automatically searches the termcap file in this order for these
	       entries and then sets the ''TERM'' and the ''TERMCAP'' environ-
	       ment variables.

       +t      This option indicates that xterm should start in VT102 mode.

       -tb     This  option,  corresponding to the toolBar resource, indicates
	       that xterm should display a toolbar (or menubar) at the top  of
	       its window.  The buttons in the toolbar correspond to the popup
	       menus, e.g., control/left/mouse for "Main Options".

       +tb     This option indicates that xterm should not set up a toolbar.

       -ti term_id
	       Specify the name used by xterm to select the  correct  response
	       to terminal ID queries.	It also specifies the emulation level,
	       used to	determine  the	type  of  response  to	a  DA  control
	       sequence.   Valid values include vt52, vt100, vt101, vt102, and
	       vt220 (the "vt" is  optional).	The  default  is  vt100.   The
	       term_id	argument  specifies  the terminal ID to use.  (This is
	       the same as the decTerminalID resource).

       -tm string
	       This option specifies a series  of  terminal  setting  keywords
	       followed	 by the characters that should be bound to those func-
	       tions, similar to the stty program.   The  keywords  and	 their
	       values are described in detail in the ttyModes resource.

       -tn name
	       This  option  specifies the name of the terminal type to be set
	       in the  TERM  environment  variable.   It  corresponds  to  the
	       termName resource.  This terminal type must exist in the termi-
	       nal database (termcap or terminfo, depending on	how  xterm  is
	       built)  and  should  have li# and co# entries.  If the terminal
	       type is not found, xterm	 uses  the  built-in  list  ''xterm'',
	       ''vt102'', etc.

       -u8     This  option  sets  the utf8 resource.  When utf8 is set, xterm
	       interprets incoming data as UTF-8.   This  sets	the  wideChars
	       resource	 as  a	side-effect,  but  the	UTF-8 mode set by this
	       option prevents it from being turned off.  If you must turn  it
	       on and off, use the wideChars resource.

	       This option and the utf8 resource are overridden by the -lc and
	       -en options and locale resource.	 That is, if  xterm  has  been
	       compiled	 to  support  luit,  and  the  locale  resource is not
	       ''false'' this option is ignored.  We recommend using  the  -lc
	       option  or  the ''locale: true'' resource in UTF-8 locales when
	       your operating system supports locale, or -en UTF-8  option  or
	       the  ''locale: UTF-8'' resource when your operating system does
	       not support locale.

       +u8     This option resets the utf8 resource.

       -ulc    This option disables the display of characters  with  underline
	       attribute as color rather than with underlining.

       +ulc    This  option  enables  the display of characters with underline
	       attribute as color rather than with underlining.

       -ut     This option indicates that xterm should not write a record into
	       the the system utmp log file.

       +ut     This option indicates that xterm should write a record into the
	       system utmp log file.

       -vb     This option indicates that a visual bell is preferred  over  an
	       audible	one.   Instead of ringing the terminal bell whenever a
	       Control-G is received, the window will be flashed.

       +vb     This option indicates that a visual bell should not be used.

       -wc     This option sets the wideChars  resource.   When	 wideChars  is
	       set, xterm maintains internal structures for 16-bit characters.
	       If you do not set this resource to ''true'', xterm will	ignore
	       the  escape  sequence  which  turns UTF-8 mode on and off.  The
	       default is ''false''.

       +wc     This option resets the wideChars resource.

       -wf     This option indicates that xterm should wait for the window  to
	       be mapped the first time before starting the subprocess so that
	       the initial terminal size settings  and	environment  variables
	       are  correct.   It is the application's responsibility to catch
	       subsequent terminal size changes.

       +wf     This option indicates that xterm should not wait before	start-
	       ing the subprocess.

       -ziconbeep percent
	       Same  as	 zIconBeep  resource.	If percent is non-zero, xterms
	       that produce output while iconified will cause an  XBell	 sound
	       at  the	given  volume  and  have "***" prepended to their icon
	       titles.	Most window managers will detect this  change  immedi-
	       ately,  showing	you  which  window has the output.  (A similar
	       feature was in x10 xterm.)

       -C      This option indicates that this window should  receive  console
	       output.	 This is not supported on all systems.	To obtain con-
	       sole output, you must be the owner of the console  device,  and
	       you  must  have	read  and write permission for it.  If you are
	       running X under xdm on the console screen you may need to  have
	       the  session  startup  and reset programs explicitly change the
	       ownership of the console device in order to get this option  to
	       work.

       -Sccn   This  option  allows  xterm  to	be used as an input and output
	       channel for an existing program and is sometimes used  in  spe-
	       cialized applications.  The option value specifies the last few
	       letters of the name of a pseudo-terminal to use in slave	 mode,
	       plus  the  number  of  the  inherited  file descriptor.	If the
	       option contains a ''/'' character, that delimits the characters
	       used  for  the  pseudo-terminal	name from the file descriptor.
	       Otherwise, exactly two characters are used from the option  for
	       the pseudo-terminal name, the remainder is the file descriptor.
	       Examples:
		      -S123/45
		      -Sab34

	       Note that xterm does not close any file descriptor which it did
	       not  open for its own use.  It is possible (though probably not
	       portable) to have an application	 which	passes	an  open  file
	       descriptor  down	 to  xterm  past  the initialization or the -S
	       option to a process running in the xterm.

       The following command line arguments  are  provided  for	 compatibility
       with  older versions.  They may not be supported in the next release as
       the X Toolkit provides standard options that accomplish the same	 task.

       %geom   This  option  specifies	the preferred size and position of the
	       Tektronix window.  It is shorthand for specifying the ''*tekGe-
	       ometry'' resource.

	#geom  This  option  specifies the preferred position of the icon win-
	       dow.  It is  shorthand  for  specifying	the  ''*iconGeometry''
	       resource.

       -T string
	       This  option  specifies	the  title for xterm's windows.	 It is
	       equivalent to -title.

       -n string
	       This option specifies the icon name for xterm's windows.	 It is
	       shorthand for specifying the ''*iconName'' resource.  Note that
	       this is not the same as the toolkit option -name	 (see  below).
	       The default icon name is the application name.

       -r      This option indicates that reverse video should be simulated by
	       swapping the foreground and background colors.  It  is  equiva-
	       lent to -rv.

       -w number
	       This  option  specifies	the width in pixels of the border sur-
	       rounding the window.  It is equivalent to -borderwidth or  -bw.

       The  following  standard	 X Toolkit command line arguments are commonly
       used with xterm:

       -bd color
	       This option specifies the color to use for the  border  of  the
	       window.	 xterm	uses  the  X Toolkit default, which is ''XtDe-
	       faultForeground''.

       -bg color
	       This option specifies the color to use for  the	background  of
	       the window.  The default is ''XtDefaultBackground.''

       -bw number
	       This  option  specifies	the width in pixels of the border sur-
	       rounding the window.

       -display display
	       This  option  specifies	the   X	  server   to	contact;   see
	       X(el5_4.1-root-mockbuild/usr/share/man/xterm.1).

       -fg color
	       This  option  specifies	the  color to use for displaying text.
	       The default is ''XtDefaultForeground.''

       -fn font
	       This option specifies the font to be used for displaying normal
	       text.  The default is fixed.

       -font font
	       This is the same as -fn.

       -geometry geometry
	       This  option  specifies	the preferred size and position of the
	       VT102	     window;	     see	  X(el5_4.1-root-mock-
	       build/usr/share/man/xterm.1).

       -iconic This  option indicates that xterm should ask the window manager
	       to start it as an icon rather than as the normal window.

       -name name
	       This  option  specifies	the  application  name	 under	 which
	       resources  are  to  be  obtained,  rather than the default exe-
	       cutable file name.  Name should	not  contain  ''.''  or	 ''*''
	       characters.

       -rv     This option indicates that reverse video should be simulated by
	       swapping the foreground and background colors.

       +rv     Disable the simulation of reverse video by swapping  foreground
	       and background colors.

       -title string
	       This  option  specifies	the  window title string, which may be
	       displayed by window managers  if	 the  user  so	chooses.   The
	       default	title  is  the	command	 line  specified  after the -e
	       option, if any, otherwise the application name.

       -xrm resourcestring
	       This option specifies a resource string to be  used.   This  is
	       especially  useful for setting resources that do not have sepa-
	       rate command line options.

RESOURCES
       The program understands all of the core X Toolkit  resource  names  and
       classes.	 Application specific resources (e.g., "XTerm.NAME") follow:

       backarrowKeyIsErase (class BackarrowKeyIsErase)
	       Tie   the  VTxxx	 backarrowKey  and  ptyInitialErase  resources
	       together by setting the DECBKM state according to  whether  the
	       initial	value of stty erase is a backspace (8) or delete (127)
	       character.  The default is ''false'', which disables this  fea-
	       ture.

       hold (class Hold)
	       If true, xterm will not immediately destroy its window when the
	       shell command completes.	 It will wait until you use the window
	       manager	to  destroy/kill  the  window,	or if you use the menu
	       entries that send a signal, e.g., HUP or KILL.  You may	scroll
	       back,  select text, etc., to perform most graphical operations.
	       Resizing the  display  will  lose  data,	 however,  since  this
	       involves interaction with the shell which is no longer running.

       hpFunctionKeys (class HpFunctionKeys)
	       Specifies whether or not HP Function Key escape codes should be
	       generated   for	 function  keys	 instead  of  standard	escape
	       sequences.  See also the keyboardType resource.

       iconGeometry (class IconGeometry)
	       Specifies the preferred size and position  of  the  application
	       when  iconified.	  It  is  not necessarily obeyed by all window
	       managers.

       iconName (class IconName)
	       Specifies the icon name.	 The default is the application	 name.

       keyboardType (class KeyboardType)
	       Enables	one  (or none) of the various keyboard-type resources:
	       hpFunctionKeys, scoFunctionKeys,	 sunFunctionKeys  and  sunKey-
	       board.  The resource's value should be one of the corresponding
	       strings hp, sco, sun or vt220.  The  individual	resources  are
	       provided for legacy support; this resource is simpler to use.

       maxBufSize (class MaxBufSize)
	       Specify	the  maximum size of the input buffer.	The default is
	       32768.  You cannot set this to a value less than the minBufSize
	       resource.   It  will  be increased as needed to make that value
	       evenly divide this one.

	       On some systems you may want to increase one  or	 both  of  the
	       maxBufSize  and	minBufSize  resource  values to achieve better
	       performance if  the  operating  system  prefers	larger	buffer
	       sizes.

       messages (class Messages)
	       Specifies  whether write access to the terminal is allowed ini-
	       tially.	See mesg(1).  The default is ''true''.

       minBufSize (class MinBufSize)
	       Specify the minimum size of the input buffer, i.e., the	amount
	       of data that xterm requests on each read.  The default is 4096.
	       You cannot set this to a value less than 64.

       ptyHandshake (class PtyHandshake)
	       If ''true'', xterm will perform handshaking during  initializa-
	       tion  to	 ensure that the parent and child processes update the
	       utmp and stty state.  The default is ''true''.

       ptyInitialErase (class PtyInitialErase)
	       If ''true'', xterm will use the pseudo-terminal's sense of  the
	       stty  erase value.  If ''false'', xterm will set the stty erase
	       value to match its own configuration, using the kb string  from
	       the  termcap  entry  as	a  reference, if available.  In either
	       case, the result is applied to the TERMCAP variable which xterm
	       sets.  The default is ''false''.

       sameName (class SameName)
	       If  the value of this resource is ''true'', xterm does not send
	       title and icon name change requests when the request would have
	       no  effect: the name is not changed.  This has the advantage of
	       preventing flicker and the disadvantage of requiring  an	 extra
	       round  trip  to	the server to find out the previous value.  In
	       practice this should  never  be	a  problem.   The  default  is
	       ''true''.

       scoFunctionKeys (class ScoFunctionKeys)
	       Specifies  whether  or not SCP Function Key escape codes should
	       be generated for	 function  keys	 instead  of  standard	escape
	       sequences.  See also the keyboardType resource.

       sessionMgt (class SessionMgt)
	       If  the	value of this resource is ''true'', xterm sets up ses-
	       sion manager callbacks for XtNdieCallback and  XtNsaveCallback.
	       The default is ''true''.

       sunFunctionKeys (class SunFunctionKeys)
	       Specifies  whether  or not Sun Function Key escape codes should
	       be generated for	 function  keys	 instead  of  standard	escape
	       sequences.  See also the keyboardType resource.

       sunKeyboard (class SunKeyboard)
	       Specifies  whether  or  not  Sun/PC  keyboard  layout should be
	       assumed rather than DEC VT220.  This causes the keypad  '+'  to
	       be mapped to ','.  and CTRL F1-F12 to F11-F20, depending on the
	       setting of the ctrlFKeys resource.  so  xterm  emulates	a  DEC
	       VT220  more  accurately.	  Otherwise (the default, with sunKey-
	       board set to ''false''), xterm uses PC-style bindings  for  the
	       function keys and keypad.

	       PC-style	 bindings use the Shift, Alt, Control and Meta keys as
	       modifiers for function-keys and keypad (see the document	 Xterm
	       Control	Sequences  for	details).   The	 PC-style bindings are
	       analogous to PCTerm, but not the same  thing.   Normally	 these
	       bindings	 do  not  conflict  with  the  use  of the Meta key as
	       described for the eightBitInput resource.   If  they  do,  note
	       that  the  PC-style bindings are evaluated first.  See also the
	       keyboardType resource.

       termName (class TermName)
	       Specifies the terminal type name to be set in the TERM environ-
	       ment variable.

       title (class Title)
	       Specifies  a string that may be used by the window manager when
	       displaying this application.

       toolBar (class ToolBar)
	       Specifies whether or not the toolbar should be displayed.   The
	       default is ''true.''

       ttyModes (class TtyModes)
	       Specifies a string containing terminal setting keywords and the
	       characters to which they	 may  be  bound.   Allowable  keywords
	       include:	 brk,  dsusp,  eof,  eol,  eol2, erase, erase2, flush,
	       intr, kill, lnext, quit,	 rprnt,	 start,	 status,  stop,	 susp,
	       swtch  and weras.  Control characters may be specified as ^char
	       (e.g., ^c or ^u) and ^? may be used to indicate	delete	(127).
	       Use ^- to denote undef.	Use \034 to represent ^\, since a lit-
	       eral backslash in an X resource escapes the next character.

	       This is very useful for overriding the  default	terminal  set-
	       tings  without  having  to  do  an  stty every time an xterm is
	       started.	 Note, however, that the stty program on a given  host
	       may use different keywords; xterm's table is built-in.

       useInsertMode (class UseInsertMode)
	       Force  use  of insert mode by adding appropriate entries to the
	       TERMCAP environment variable.  This is  useful  if  the	system
	       termcap is broken.  The default is ''false.''

       utmpDisplayId (class UtmpDisplayId)
	       Specifies whether or not xterm should try to record the display
	       identifier (display number and screen number) as	 well  as  the
	       hostname in the system utmp log file.  The default is ''true.''

       utmpInhibit (class UtmpInhibit)
	       Specifies whether or not xterm should try to record the	user's
	       terminal	 in the system utmp log file.  If true, xterm will not
	       try.  The default is ''false.''

       waitForMap (class WaitForMap)
	       Specifies whether or not xterm should wait for the initial win-
	       dow  map	 before	 starting  the	subprocess.   The  default  is
	       ''false.''

       zIconBeep (class ZIconBeep)
	       Same as -ziconbeep command line argument.  If the value of this
	       resource	 is  non-zero, xterms that produce output while iconi-
	       fied will cause an XBell sound at the  given  volume  and  have
	       "***"  prepended	 to  their  icon titles.  Most window managers
	       will detect this change immediately, showing you	 which	window
	       has  the	 output.   (A  similar feature was in x10 xterm.)  The
	       default is ''false.''

       The following resources are specified  as  part	of  the	 vt100	widget
       (class	 VT100):   These   are	 specified   by	  patterns   such   as
       "XTerm.vt100.NAME":

       activeIcon (class ActiveIcon)
	       Specifies whether or not active icon windows  are  to  be  used
	       when the xterm window is iconified, if this feature is compiled
	       into xterm.  The active icon is a miniature  representation  of
	       the  content  of	 the  window  and  will	 update as the content
	       changes.	 Not all window managers necessarily support  applica-
	       tion  icon  windows.   Some  window  managers will allow you to
	       enter keystrokes into the active icon window.  The  default  is
	       ''false.''

       allowC1Printable (class AllowC1Printable)
	       If  true,  overrides the mapping of C1 controls (codes 128-159)
	       to make them be treated as if they were	printable  characters.
	       Although this corresponds to no particular standard, some users
	       insist it is a VT100.  The default is ''false.''

       allowSendEvents (class AllowSendEvents)
	       Specifies whether or not synthetic key and button events	 (gen-
	       erated using the X protocol SendEvent request) should be inter-
	       preted or discarded.  The default is ''false'' meaning they are
	       discarded.  Note that allowing such events creates a very large
	       security hole.  The default is ''false.''

       allowWindowOps (class AllowWindowOps)
	       Specifies whether extended window control sequences (as used in
	       dtterm) for should be allowed.  The default is ''true.''

       alwaysHighlight (class AlwaysHighlight)
	       Specifies  whether  or  not xterm should always display a high-
	       lighted text cursor.  By default (if this resource is false), a
	       hollow  text cursor is displayed whenever the pointer moves out
	       of the window or the window loses the input focus.  The default
	       is ''false.''

       alwaysUseMods (class AlwaysUseMods)
	       Override the numLock resource, telling xterm to use the Alt and
	       Meta  modifiers	to  construct  parameters  for	function   key
	       sequences  even	if  those modifiers appear in the translations
	       resource.  The default is ''false.''

       answerbackString (class AnswerbackString)
	       Specifies the string that xterm sends in	 response  to  an  ENQ
	       (control/E)  character  from  the host.	The default is a blank
	       string, i.e., ''''.  A hardware VT100 implements	 this  feature
	       as a setup option.

       appcursorDefault (class AppcursorDefault)
	       If ''true,'' the cursor keys are initially in application mode.
	       This is the same as the VT102 private DECCKM mode, The  default
	       is ''false.''

       appkeypadDefault (class AppkeypadDefault)
	       If ''true,'' the keypad keys are initially in application mode.
	       The default is ''false.''

       autoWrap (class AutoWrap)
	       Specifies whether or not	 auto-wraparound  should  be  enabled.
	       This is the same as the VT102 DECAWM.  The default is ''true.''

       awaitInput (class AwaitInput)
	       Specifies whether or not the xterm uses a 50 millisecond	 time-
	       out   to	  await	 input	(i.e.,	to  support  the  Xaw3d	 arrow
	       scrollbar).  The default is ''false.''

       backarrowKey (class BackarrowKey)
	       Specifies whether the backarrow key transmits a	backspace  (8)
	       or delete (127) character.  This corresponds to the DECBKM con-
	       trol sequence.  The default (backspace) is ''true.''   Pressing
	       the control key toggles this behavior.

       background (class Background)
	       Specifies  the  color  to use for the background of the window.
	       The default is ''XtDefaultBackground.''

       bellOnReset (class BellOnReset)
	       Specifies whether to sound a bell when doing a hard reset.  The
	       default is ''true.''

       bellSuppressTime (class BellSuppressTime)
	       Number  of  milliseconds	 after	a  bell command is sent during
	       which additional bells will be suppressed.  Default is 200.  If
	       set  non-zero,  additional  bells will also be suppressed until
	       the server reports that processing of the first bell  has  been
	       completed; this feature is most useful with the visible bell.

       boldColors (class ColorMode)
	       Specifies  whether  to  combine bold attribute with colors like
	       the IBM PC, i.e., map colors 0 through 7 to  colors  8  through
	       15.   These  normally  are the brighter versions of the first 8
	       colors, hence bold.  The default is ''true.''

       boldFont (class BoldFont)
	       Specifies the name of the bold font to  use  instead  of	 over-
	       striking.  There is no default for this resource.

       boldMode (class BoldMode)
	       This  specifies	whether	 or  not  text with the bold attribute
	       should be overstruck to simulate bold  fonts  if	 the  resolved
	       bold  font is the same as the normal font.  It may be desirable
	       to disable bold fonts when color is being  used	for  the  bold
	       attribute.  Note that xterm has one bold font which you may set
	       explicitly.  It attempts to match a bold	 font  for  the	 other
	       font  selections (font1 through font6).	If the normal and bold
	       fonts are distinct, this resource has no effect.	  The  default
	       is ''true.''

	       Although	 xterm	attempts  to  match a bold font for other font
	       selections, the font server may not  cooperate.	 Since	X11R6,
	       bitmap  fonts have been scaled.	The font server claims to pro-
	       vide the bold font that xterm requests, but the result  is  not
	       always  readable.  XFree86 provides a feature which can be used
	       to suppress the scaling.	 In the X server's configuration  file
	       (e.g.,  /etc/X11/xorg.conf), you can add ":unscaled" to the end
	       of the directory specification for the "misc" fonts, which com-
	       prise  the fixed-pitch fonts that are used by xterm.  For exam-
	       ple
		    FontPath  "/usr/share/X11/fonts"

	       would become
		    FontPath  "/usr/share/X11/fonts/misc/:unscaled"

	       Depending on your configuration, the font server may  have  its
	       own  configuration  file.  The same ":unscaled" can be added to
	       its configuration file at the end of the	 directory  specifica-
	       tion for "misc".

       brokenLinuxOSC (class BrokenLinuxOSC)
	       If true, xterm applies a workaround to ignore malformed control
	       sequences that a Linux script might send.  Compare the  palette
	       control	sequences  documented  in  console_codes with ECMA-48.
	       The default is ''true.''

       brokenSelections (class BrokenSelections)
	       If true, xterm in 8-bit mode will interpret  STRING  selections
	       as  carrying  text  in the current locale's encoding.  Normally
	       STRING selections carry ISO-8859-1 encoded text.	 Setting  this
	       resource	 to  ''true''  violates the ICCCM; it may, however, be
	       useful for interacting with some broken X clients.  The default
	       is ''false.''

       brokenStringTerm (class BrokenStringTerm)
	       provides	 a  work-around	 for  some ISDN routers which start an
	       application control string without completing it.  Set this  to
	       ''true''	 if  xterm  appears  to	 freeze	 when connecting.  The
	       default is ''false.''

       c132 (class C132)
	       Specifies whether or not the  VT102  DECCOLM  escape  sequence,
	       used  to	 switch between 80 and 132 columns, should be honored.
	       The default is ''false.''

       cacheDoublesize (class CacheDoublesize)
	       Specifies the maximum number of double-sized  fonts  which  are
	       cached  by  xterm.  The default (8) may be too large for some X
	       terminals with limited memory.  Set this	 to  zero  to  disable
	       doublesize fonts altogether.

       charClass (class CharClass)
	       Specifies  comma-separated lists of character class bindings of
	       the form [low-]high:value.  These are used in determining which
	       sets  of	 characters  should be treated the same when doing cut
	       and paste.  See the CHARACTER CLASSES section.

       cjkWidth (class CjkWidth)
	       Specifies whether xterm	should	follow	the  traditional  East
	       Asian  width  convention.  When turned on, characters with East
	       Asian Ambiguous (A) category in UTR 11 have a column  width  of
	       2.   You	 may  have  to set this option to ''true'' if you have
	       some old East Asian terminal based programs  that  assume  that
	       line-drawing  characters have a column width of 2.  The default
	       is ''false.''

       color0 (class Color0)

       color1 (class Color1)

       color2 (class Color2)

       color3 (class Color3)

       color4 (class Color4)

       color5 (class Color5)

       color6 (class Color6)

       color7 (class Color7)
	       These specify the colors	 for  the  ISO	6429  extension.   The
	       defaults	 are,  respectively,  black,  red3, green3, yellow3, a
	       customizable dark  blue,	 magenta3,  cyan3,  and	 gray90.   The
	       default	shades of color are chosen to allow the colors 8-15 to
	       be used as brighter versions.

       color8 (class Color8)

       color9 (class Color9)

       color10 (class Color10)

       color11 (class Color11)

       color12 (class Color12)

       color13 (class Color13)

       color14 (class Color14)

       color15 (class Color15)
	       These specify the colors for the ISO 6429 extension if the bold
	       attribute  is  also  enabled.   The default resource values are
	       respectively, gray30, red, green, yellow, a customizable	 light
	       blue, magenta, cyan, and white.

       color16 (class Color16)

       through

       color255 (class Color255)
	       These  specify  the  colors  for	 the 256-color extension.  The
	       default resource values are for colors 16 through 231 to make a
	       6x6x6  color  cube,  and	 colors	 232  through  255  to	make a
	       grayscale ramp.

       colorAttrMode (class ColorAttrMode)
	       Specifies whether colorBD, colorBL, colorRV, and colorUL should
	       override ANSI colors.  If not, these are displayed only when no
	       ANSI colors have been set for the corresponding position.   The
	       default is ''false.''

       colorBD (class ColorBD)
	       This  specifies	the color to use to display bold characters if
	       the  ''colorBDMode''  resource  is  enabled.   The  default  is
	       ''XtDefaultForeground.''

       colorBDMode (class ColorAttrMode)
	       Specifies  whether characters with the bold attribute should be
	       displayed in color or as bold characters.   Note	 that  setting
	       colorMode off disables all colors, including bold.  The default
	       is ''false.''

       colorBL (class ColorBL)
	       This specifies the color to use to display blink characters  if
	       the  ''colorBLMode''  resource  is  enabled.   The  default  is
	       ''XtDefaultForeground.''

       colorBLMode (class ColorAttrMode)
	       Specifies whether characters with the blink attribute should be
	       displayed  in  color.  Note that setting colorMode off disables
	       all colors, including this.  The default is ''false.''

       colorMode (class ColorMode)
	       Specifies whether or not recognition of ANSI (ISO  6429)	 color
	       change  escape  sequences  should  be  enabled.	The default is
	       ''true.''

       colorRV (class ColorRV)
	       This specifies the color to use to display  reverse  characters
	       if  the	''colorRVMode''	 resource  is enabled.	The default is
	       ''XtDefaultForeground.''

       colorRVMode (class ColorAttrMode)
	       Specifies whether characters with the reverse attribute	should
	       be  displayed  in  color.  Note that setting colorMode off dis-
	       ables all colors, including this.  The default is ''false.''

       colorUL (class ColorUL)
	       This specifies the color to use to display  underlined  charac-
	       ters  if	 the ''colorULMode'' resource is enabled.  The default
	       is ''XtDefaultForeground.''

       colorULMode (class ColorAttrMode)
	       Specifies  whether  characters  with  the  underline  attribute
	       should be displayed in color or as underlined characters.  Note
	       that setting  colorMode	off  disables  all  colors,  including
	       underlining.  The default is ''false.''

       ctrlFKeys (class CtrlFKeys)
	       In  VT220  keyboard  mode (see sunKeyboard resource), specifies
	       the amount by which to shift F1-F12 given  a  control  modifier
	       (CTRL).	This allows you to generate key symbols for F10-F20 on
	       a Sun/PC keyboard.  The default is  ''10'',  which  means  that
	       CTRL F1 generates the key symbol for F11.

       curses (class Curses)
	       Specifies  whether or not the last column bug in more(1) should
	       be worked around.  See the -cu option for details.  The default
	       is ''false.''

       cursorBlink (class CursorBlink)
	       Specifies  whether  to  make  the cursor blink.	The default is
	       ''false.''

       cursorColor (class CursorColor)
	       Specifies the color to use for the text cursor.	The default is
	       ''XtDefaultForeground.''	  Xterm	 attempts  to  keep this color
	       from being the same as the background color, since it draws the
	       cursor  by  filling  the	 background  of a text cell.  The same
	       restriction applies to control sequences which may change  this
	       color.

       cursorOffTime (class CursorOffTime)
	       Specifies  the  duration	 of the "off" part of the cursor blink
	       cycle-time in milliseconds.  The same timer is  used  for  text
	       blinking.  The default is 300.

       cursorOnTime (class CursorOnTime)
	       Specifies  the  duration	 of  the "on" part of the cursor blink
	       cycle-time, in milliseconds.  The same timer is used  for  text
	       blinking.  The default is 600.

       cutNewline (class CutNewline)
	       If ''false'', triple clicking to select a line does not include
	       the Newline at the end of the line.  If ''true'',  the  Newline
	       is selected.  The default is ''true.''

       cutToBeginningOfLine (class CutToBeginningOfLine)
	       If  ''false'',  triple  clicking	 to select a line selects only
	       from the current word forward.  If ''true'', the entire line is
	       selected.  The default is ''true.''

       decTerminalID (class DecTerminalID)
	       Specifies  the  emulation  level	 (100=VT100, 220=VT220, etc.),
	       used to	determine  the	type  of  response  to	a  DA  control
	       sequence.   Leading  non-digit  characters  are	ignored, e.g.,
	       "vt100" and "100" are the same.	The default is 100.

       deleteIsDEL (class DeleteIsDEL)
	       Specifies whether the Delete key on the editing	keypad	should
	       send  DEL (127) or the VT220-style Remove escape sequence.  The
	       default is ''false,'' for the latter.

       dynamicColors (class DynamicColors)
	       Specifies whether or not	 escape	 sequences  to	change	colors
	       assigned to different attributes are recognized.

       eightBitControl (class EightBitControl)
	       Specifies whether or not control sequences sent by the terminal
	       should  be  eight-bit  characters  or  escape  sequences.   The
	       default is ''false.''

       eightBitInput (class EightBitInput)
	       If  ''true'', Meta characters (a single-byte character combined
	       with the keys modifier key) input from the  keyboard  are  pre-
	       sented  as  a  single  character with the eighth bit turned on.
	       The terminal is put into 8-bit mode.  If ''false'', Meta	 char-
	       acters  are  converted  into  a two-character sequence with the
	       character itself preceded by ESC.  On startup, xterm  tries  to
	       put the terminal into 7-bit mode.  The metaSendsEscape resource
	       may override this.  The default is ''true.''

	       Generally keyboards do not have a key labeled "Meta", but "Alt"
	       keys  are  common, and they are conventionally used for "Meta".
	       If they were synonymous, it would have been reasonable to  name
	       this  resource "altSendsEscape", reversing its sense.  For more
	       background on this, see the meta function in curses.

	       Note that the Alt key is not necessarily the same as  the  Meta
	       modifier.   xmodmap  lists your key modifiers.  X defines modi-
	       fiers for shift, (caps) lock and control, as well  as  5	 addi-
	       tional modifiers which are generally used to configure key mod-
	       ifiers.	xterm inspects the same information to find the	 modi-
	       fier  associated with either Meta key (left or right), and uses
	       that key as the Meta modifier.  It also looks for  the  NumLock
	       key, to recognize the modifier which is associated with that.

	       If  your	 xmodmap configuration uses the same keycodes for Alt-
	       and Meta-keys, xterm will only  see  the	 Alt-key  definitions,
	       since  those  are  tested  before Meta-keys.  NumLock is tested
	       first.  It is important to keep these keys distinct;  otherwise
	       some of xterm's functionality is not available.

       eightBitOutput (class EightBitOutput)
	       Specifies  whether  or  not  eight-bit characters sent from the
	       host should be accepted as is or stripped  when	printed.   The
	       default	is ''true,'' which means that they are accepted as is.

       faceName (class FaceName)
	       Specify the  pattern  for  fonts	 selected  from	 the  FreeType
	       library	if  support  for that library was compiled into xterm.
	       There is no default.  If not specified, or if there is no match
	       for both normal and bold fonts, xterm uses the font and related
	       resources.

       faceNameDoublesize (class FaceNameDoublesize)
	       Specify an double-width font for	 cases	where  an  application
	       requires this, e.g., in CJK applications.  There is no default.
	       If  the	application  uses  double-wide	characters  and	  this
	       resource	 is not given, xterm  will use a scaled version of the
	       font given by faceName.

       faceSize (class FaceSize)
	       Specify the pointsize for  fonts	 selected  from	 the  FreeType
	       library	if  support  for that library was compiled into xterm.
	       The default is ''14.''

       font (class Font)
	       Specifies  the  name  of	 the  normal  font.   The  default  is
	       ''fixed.''

	       See  the discussion of the locale resource, which describes how
	       this font may be overridden.

	       NOTE: some resource files use patterns such as
	       *font: fixed

	       which are overly broad, affecting both
	       xterm.vt100.font

	       and
	       xterm.vt100..utf8fonts.font

	       which is probably not what you intended.

       font1 (class Font1)
	       Specifies the name of the first alternative font.

       font2 (class Font2)
	       Specifies the name of the second alternative font.

       font3 (class Font3)
	       Specifies the name of the third alternative font.

       font4 (class Font4)
	       Specifies the name of the fourth alternative font.

       font5 (class Font5)
	       Specifies the name of the fifth alternative font.

       font6 (class Font6)
	       Specifies the name of the sixth alternative font.

       fontDoublesize (class FontDoublesize)
	       Specifies whether xterm should attempt to use font  scaling  to
	       draw  doublesize characters.  Some older font servers cannot do
	       this  properly,	will  return  misleading  font	metrics.   The
	       default	is ''true''.  If disabled, xterm will simulate double-
	       size  characters	 by  drawing  normal  characters  with	spaces
	       between them.

       forceBoxChars (class ForceBoxChars)
	       Specifies whether xterm should assume the normal and bold fonts
	       have VT100 line-drawing characters:

	       -    The fixed-pitch ISO-8859-*-encoded	fonts  used  by	 xterm
		    normally have the VT100 line-drawing glyphs in cells 1-31.
		    Other fixed-pitch fonts may be more attractive,  but  lack
		    these glyphs.

	       -    When  using an ISO-10646-1 font and the wideChars resource
		    is true, xterm uses the Unicode  glyphs  which  match  the
		    VT100 line-drawing glyphs.

	       If  ''false'',  xterm checks for missing glyphs in the font and
	       makes line-drawing characters directly as needed.  If ''true'',
	       xterm  uses  whatever  is  in  the  font without checking.  The
	       default is ''false.''

       foreground (class Foreground)
	       Specifies the color to use for displaying text in  the  window.
	       Setting	the class name instead of the instance name is an easy
	       way to have everything that would normally appear in  the  text
	       color change color.  The default is ''XtDefaultForeground.''

       freeBoldBox (class freeBoldBox)
	       Specifies  whether  xterm  should assume the bounding boxes for
	       normal and bold fonts are compatible.  If ''false'', xterm com-
	       pares  them  and	 will reject choices of bold fonts that do not
	       match the size of the normal font.  The default	is  ''false'',
	       which means that the comparison is performed.

       geometry (class Geometry)
	       Specifies  the preferred size and position of the VT102 window.
	       There is no default for this resource.

       highlightColor (class HighlightColor)
	       Specifies the color to use for the background  of  selected  or
	       otherwise highlighted text.  If not specified, reverse video is
	       used.  The default is ''XtDefaultForeground.''

       highlightSelection (class HighlightSelection)
	       If ''false'', selecting with the mouse highlights all positions
	       on  the	screen	between the beginning of the selection and the
	       current position.  If ''true'', xterm highlights only the posi-
	       tions  that  contain text that can be selected.	The default is
	       ''false.''

	       Depending on the way your applications  write  to  the  screen,
	       there  may  be trailing blanks on a line.  Xterm stores data as
	       it is shown on the screen.  Erasing  the	 display  changes  the
	       internal state of each cell so it is not considered a blank for
	       the purpose of selection.  Blanks written since the last	 erase
	       are  selectable.	 If you do not wish to have trailing blanks in
	       a selection, use the trimSelection resource.

       hpLowerleftBugCompat (class HpLowerleftBugCompat)
	       Specifies whether to work around	 a  bug	 in  HP's  xdb,	 which
	       ignores	termcap	 and  always  sends ESC F to move to the lower
	       left corner.  ''true'' causes xterm to interpret	 ESC  F	 as  a
	       request	to  move  to the lower left corner of the screen.  The
	       default is ''false.''

       i18nSelections (class I18nSelections)
	       If false, xterm will never request the targets COMPOUND_TEXT or
	       TEXT.  The default is ''true.'' It may be set to false in order
	       to work around ICCCM violations by other X clients.

       iconBorderColor (class BorderColor)
	       Specifies the border color for the active icon window  if  this
	       feature	is  compiled into xterm.  Not all window managers will
	       make the icon border visible.

       iconBorderWidth (class BorderWidth)
	       Specifies the border width for the active icon window  if  this
	       feature	is  compiled  into  xterm.  The default is 2.  Not all
	       window managers will make the border visible.

       iconFont (class IconFont)
	       Specifies the font for the miniature  active  icon  window,  if
	       this feature is compiled into xterm.  The default is "nil2".

       internalBorder (class BorderWidth)
	       Specifies  the  number of pixels between the characters and the
	       window border.  The default is 2.

       italicULMode (class ColorAttrMode)
	       Specifies  whether  characters  with  the  underline  attribute
	       should  be displayed in an italic font or as underlined charac-
	       ters.

       jumpScroll (class JumpScroll)
	       Specifies whether or not jump scroll should be used.  This cor-
	       responds	 to  the  VT102	 DECSCLM private mode.	The default is
	       ''true.''

       keyboardDialect (class KeyboardDialect)
	       Specifies the initial keyboard dialect, as well as the  default
	       value  when the terminal is reset.  The value given is the same
	       as the final character in the control  sequences	 which	change
	       character  sets.	 The default is ''B'', which corresponds to US
	       ASCII.

       nameKeymap (class NameKeymap)
	       See the discussion of the keymap() action.

       limitResize (class LimitResize)
	       Limits resizing of the screen via control sequence to  a	 given
	       multiple of the display dimensions.  The default is ''1''.

       locale (class Locale)
	       Specifies  how to use luit, an encoding converter between UTF-8
	       and locale encodings.  The resource value (ignoring  case)  may
	       be:

	       true
		   xterm  will	use  the  encoding  specified  by  the	users'
		   LC_CTYPE locale (i.e., LC_ALL, LC_CTYPE, or LANG variables)
		   as  far  as	possible.  This is realized by always enabling
		   UTF-8 mode and invoking luit in non-UTF-8 locales.

	       medium
		   xterm will follow users' LC_CTYPE locale  only  for	UTF-8,
		   east	 Asian, and Thai locales, where the encodings were not
		   supported by conventional 8bit mode	with  changing	fonts.
		   For other locales, xterm will use conventional 8bit mode.

	       checkfont
		   If  mini-luit is compiled-in, xterm will check if a Unicode
		   font has been specified.  If so, it checks if the character
		   encoding  for  the  current	locale	is  POSIX,  Latin-1 or
		   Latin-9, uses the appropriate mapping to support those with
		   the	Unicode font.  For other encodings, xterm assumes that
		   UTF-8 encoding is required.

	       false
		   xterm will use conventional 8bit mode or UTF-8 mode accord-
		   ing to utf8 resource or -u8 option.

	       Any  other  value, e.g., ''UTF-8'' or ''ISO8859-2'', is assumed
	       to be an encoding name; luit will be  invoked  to  support  the
	       encoding.   The	actual	list of supported encodings depends on
	       luit.  The default is ''medium''.

	       Regardless of your locale and encoding, you need an ISO-10646-1
	       font to display the result.  Your configuration may not include
	       this font, or locale-support by xterm may not  be  needed.   At
	       startup,	 xterm	uses  a	 mechanism  equivalent to the load-vt-
	       fonts(utf8Fonts, Utf8Fonts) action to  load  font  name	subre-
	       sources	of  the VT100 widget.  That is, resource patterns such
	       as  "*vt100.utf8Fonts.font"  will  be  loaded,  and  (if	  this
	       resource	 is enabled), override the normal fonts.  If no subre-
	       sources are found, the  normal  fonts  such  as	"*vt100.font",
	       etc.,  are used.	 The resource files distributed with xterm use
	       ISO-10646-1 fonts, but do not rely on them unless you are using
	       the locale mechanism.

       localeFilter (class LocaleFilter)
	       Specifies  the  file  name  for	the encoding converter from/to
	       locale encodings and UTF-8 which is used with the -lc option or
	       locale  resource.   The	help  message shown by ''xterm -help''
	       lists the default value, which depends on your system  configu-
	       ration.

       loginShell (class LoginShell)
	       Specifies  whether  or  not  the	 shell to be run in the window
	       should be started as a login shell.  The default is  ''false.''

       marginBell (class MarginBell)
	       Specifies  whether or not the bell should be rung when the user
	       types near the right margin.  The default is ''false.''

       metaSendsEscape (class MetaSendsEscape)
	       If ''true'', Meta characters (a	character  combined  with  the
	       Meta  modifier key) are converted into a two-character sequence
	       with the character itself preceded by  ESC.   This  applies  as
	       well  to function key control sequences, unless xterm sees that
	       Meta is used in your  key  translations.	  If  ''false'',  Meta
	       characters input from the keyboard are handled according to the
	       eightBitInput resource.	The default is ''false.''

       mkWidth (class MkWidth)
	       Specifies whether xterm should use a built-in  version  of  the
	       wide character width calculation.  The default is ''false.''

       modifyCursorKeys (class ModifyCursorKeys)
	       Tells  how  to  handle the special case where Control-, Shift-,
	       Alt- or Meta-modifiers are used	to  add	 a  parameter  to  the
	       escape  sequence	 returned  by  a  cursor-key.	The default is
	       ''2'':

	       Set it to 0 to use the old/obsolete behavior.
	       Set it to 1 to prefix modified sequences with CSI.
	       Set it to 2 to force the modifier to be the second parameter.
	       Set it to 3 to mark the sequence with a '>' to hint that it  is
	       private.

       modifyOtherKeys (class ModifyOtherKeys)
	       Like  modifyCursorKeys,	tells  xterm  to  construct  an escape
	       sequence for other keys (such as "2")  when  modified  by  Con-
	       trol-,  Alt- or Meta-modifiers.	This feature does not apply to
	       function keys and well-defined keys such as ESC or the  control
	       keys.  The default is ''0'':

	       Set it to 0 to disable this feature.
	       Set it to 1 to enable this feature for keys except Tab and some
	       special control character cases, e.g., Control-Space to make  a
	       NUL.
	       Set  it	to  1  to  enable  this feature for keys including the
	       exceptions listed.

       multiClickTime (class MultiClickTime)
	       Specifies the maximum time in milliseconds between  multi-click
	       select events.  The default is 250 milliseconds.

       multiScroll (class MultiScroll)
	       Specifies  whether  or  not  scrolling  should  be  done	 asyn-
	       chronously.  The default is ''false.''

       nMarginBell (class Column)
	       Specifies the number of characters from	the  right  margin  at
	       which the margin bell should be rung, when enabled.

       numLock (class NumLock)
	       If ''true'', xterm checks if NumLock is used as a modifier (see
	       xmodmap(1)).  If so, this modifier  is  used  to	 simplify  the
	       logic  when  implementing  special  NumLock for the sunKeyboard
	       resource.  Also (when sunKeyboard is false), similar  logic  is
	       used  to	 find  the modifier associated with the left and right
	       Alt keys.  The default is ''true.''

       oldXtermFKeys (class OldXtermFKeys)
	       If ''true'', xterm will use  old-style  control	sequences  for
	       function	 keys  F1  to  F4, for compatibility with X Consortium
	       xterm.  Otherwise, it uses the VT100-style  codes  for  PF1  to
	       PF4.  The default is ''false.''

       on2Clicks (class On2Clicks)

       on3Clicks (class On3Clicks)

       on4Clicks (class On4Clicks)

       on5Clicks (class On5Clicks)
	       Specify	selection  behavior  in	 response  to  multiple	 mouse
	       clicks.	 A  single  mouse  click  is  always  interpreted   as
	       described in the SELECTION section (see POINTER USAGE).	Multi-
	       ple mouse clicks (using the button which activates the  select-
	       start  action) are interpreted according to the resource values
	       of on2Clicks, etc.  The resource value can be one of these:

	       word
		  Select a ''word'' as determined by the  charClass  resource.
		  See the CHARACTER CLASSES section.

	       line
		  Select a line (counting wrapping).

	       group
		  Select  a  group of adjacent lines (counting wrapping).  The
		  selection stops on a blank line.

	       page
		  Select all visible lines, i.e., the page.

	       all
		  Select all lines, i.e., including the saved lines.

	       regex
		  Select a ''word'' as determined by  the  regular  expression
		  which follows in the resource value.

	       none
		  No selection action is associated with this resource.	 xterm
		  interprets it as the end of the list.	 For example, you  may
		  use  it  to  disable triple (and higher) clicking by setting
		  on3Clicks to ''none''.

	       The default values for on2Clicks and on3Clicks are ''word'' and
	       ''line'',   respectively.    There  is  no  default  value  for
	       on4Clicks or on5Clicks, making  those  inactive.	  On  startup,
	       xterm  determines the maximum number of clicks by the onXClicks
	       resource values which are set.

       pointerColor (class PointerColor)
	       Specifies the foreground color of the pointer.  The default  is
	       ''XtDefaultForeground.''

       pointerColorBackground (class PointerColorBackground)
	       Specifies  the background color of the pointer.	The default is
	       ''XtDefaultBackground.''

       pointerShape (class Cursor)
	       Specifies the name of the shape of the pointer.	The default is
	       ''xterm.''

       popOnBell (class PopOnBell)
	       Specifies  whether the window would be raised when Control-G is
	       received.  The default is ''false.''

       printAttributes (class PrintAttributes)
	       Specifies whether to print graphic attributes  along  with  the
	       text.   A  real	DEC  VTxxx  terminal will print the underline,
	       highlighting codes but your printer may not  handle  these.   A
	       ''0''  disables	the attributes.	 A ''1'' prints the normal set
	       of  attributes  (bold,  underline,  inverse   and   blink)   as
	       VT100-style  control  sequences.	  A  ''2''  prints  ANSI color
	       attributes as well.  The default is ''1.''

       printerAutoClose (class PrinterAutoClose)
	       If ''true'', xterm will close the printer  (a  pipe)  when  the
	       application switches the printer offline with a Media Copy com-
	       mand.  The default is ''false.''

       printerCommand (class PrinterCommand)
	       Specifies a shell command to which xterm will open a pipe  when
	       the first MC (Media Copy) command is initiated.	The default is
	       a blank string.	If the resource value  is  given  as  a	 blank
	       string, the printer is disabled.

       printerControlMode (class PrinterControlMode)
	       Specifies  the printer control mode.  A ''1'' selects autoprint
	       mode, which causes xterm to print a line from the  screen  when
	       you  move  the cursor off that line with a line feed, form feed
	       or vertical tab character, or an	 autowrap  occurs.   Autoprint
	       mode  is overridden by printer controller mode (a ''2''), which
	       causes all of the output to be directed to  the	printer.   The
	       default is ''0.''

       printerExtent (class PrinterExtent)
	       Controls	 whether  a  print page function will print the entire
	       page (true), or only the the portion within the scrolling  mar-
	       gins (false).  The default is ''false.''

       printerFormFeed (class PrinterFormFeed)
	       Controls	 whether a form feed is sent to the printer at the end
	       of a print page function.  The default is ''false.''

       renderFont (class RenderFont)
	       If xterm is built with the Xft library, this  controls  whether
	       the faceName resource is used.  The default is ''true.''

       resizeGravity (class ResizeGravity)
	       Affects the behavior when the window is resized to be taller or
	       shorter.	 NorthWest specifies that the top line of text on  the
	       screen  stay  fixed.   If the window is made shorter, lines are
	       dropped from the bottom; if the window is  made	taller,	 blank
	       lines  are  added  at  the bottom.  This is compatible with the
	       behavior in R4.	SouthWest (the	default)  specifies  that  the
	       bottom line of text on the screen stay fixed.  If the window is
	       made taller, additional saved lines will be scrolled down  onto
	       the  screen;  if	 the  window  is  made	shorter, lines will be
	       scrolled off the top of the screen, and	the  top  saved	 lines
	       will be dropped.

       reverseVideo (class ReverseVideo)
	       Specifies  whether  or  not  reverse video should be simulated.
	       The default is ''false.''

       reverseWrap (class ReverseWrap)
	       Specifies whether or not reverse-wraparound should be  enabled.
	       This  corresponds  to  xterm's private mode 45.	The default is
	       ''false.''

       rightScrollBar (class RightScrollBar)
	       Specifies whether or not the scrollbar should be	 displayed  on
	       the right rather than the left.	The default is ''false.''

       saveLines (class SaveLines)
	       Specifies  the  number  of  lines to save beyond the top of the
	       screen when a scrollbar is turned on.  The default is 64.

       scrollBar (class ScrollBar)
	       Specifies whether or not the  scrollbar	should	be  displayed.
	       The default is ''false.''

       scrollBarBorder (class ScrollBarBorder)
	       Specifies the width of the scrollbar border.  Note that this is
	       drawn to overlap the border of the xterm window.	 Modifying the
	       scrollbar's border affects only the line between the VT100 wid-
	       get and the scrollbar.  The default value is 1.

       scrollKey (class ScrollCond)
	       Specifies whether or not pressing a  key	 should	 automatically
	       cause  the  scrollbar  to  go  to  the  bottom of the scrolling
	       region.	This corresponds to xterm's private  mode  1011.   The
	       default is ''false.''

       scrollLines (class ScrollLines)
	       Specifies  the number of lines that the scroll-back and scroll-
	       forw actions should use as a default.  The default value is  1.

       scrollTtyOutput (class ScrollCond)
	       Specifies whether or not output to the terminal should automat-
	       ically cause the scrollbar to go to the bottom of the scrolling
	       region.	The default is ''true.''

       selectToClipboard (class SelectToClipboard)
	       Tells  xterm whether to use the PRIMARY or CLIPBOARD for SELECT
	       tokens in the selection mechanism.  The set-select  action  can
	       change this at runtime, allowing the user to work with programs
	       that handle only one  of	 these	mechanisms.   The  default  is
	       ''false'', which tells it to use PRIMARY.

       shiftFonts (class ShiftFonts)
	       Specifies  whether  to  enable the actions larger-vt-font() and
	       smaller-vt-font(), which are  normally  bound  to  the  shifted
	       KP_Add and KP_Subtract.	The default is ''true.''

       showBlinkAsBold (class ShowBlinkAsBold)
	       Tells  xterm  whether  to display text with blink-attribute the
	       same as bold.  If xterm has  not	 been  configured  to  support
	       blinking	 text,	the default is ''true.'', which corresponds to
	       older versions of xterm, otherwise the default is ''false.''

       showMissingGlyphs (class ShowMissingGlyphs)
	       Tells xterm whether to display a box outlining places  where  a
	       character  has been used that the font does not represent.  The
	       default is ''false.''

       signalInhibit (class SignalInhibit)
	       Specifies whether or not the entries in	the  ''Main  Options''
	       menu  for  sending  signals to xterm should be disallowed.  The
	       default is ''false.''

       tekGeometry (class Geometry)
	       Specifies the preferred size and position of the Tektronix win-
	       dow.  There is no default for this resource.

       tekInhibit (class TekInhibit)
	       Specifies whether or not the escape sequence to enter Tektronix
	       mode should be ignored.	The default is ''false.''

       tekSmall (class TekSmall)
	       Specifies whether or not the Tektronix mode window should start
	       in its smallest size if no explicit geometry is given.  This is
	       useful when running xterm on displays with small screens.   The
	       default is ''false.''

       tekStartup (class TekStartup)
	       Specifies  whether  or  not  xterm should start up in Tektronix
	       mode.  The default is ''false.''

       tiXtraScroll (class TiXtraScroll)
	       Specifies whether xterm should scroll to a new page  when  pro-
	       cessing	the ti termcap entry, i.e., the private modes 47, 1047
	       or 1049.	 This is only in effect if  titeInhibit	 is  ''true'',
	       because	the  intent  of this option is to provide a picture of
	       the full-screen application's display on the scrollback without
	       wiping  out the text that would be shown before the application
	       was initialized.	 The default for this resource is ''false.''

       titeInhibit (class TiteInhibit)
	       Specifies whether or not xterm should remove ti and te  termcap
	       entries (used to switch between alternate screens on startup of
	       many screen-oriented programs) from  the	 TERMCAP  string.   If
	       set,  xterm  also  ignores the escape sequence to switch to the
	       alternate screen.  Xterm supports terminfo in a different  way,
	       supporting  composite  control sequences (also known as private
	       modes) 1047, 1048 and 1049 which have the same  effect  as  the
	       original 47 control sequence.  The default for this resource is
	       ''false.''

       translations (class Translations)
	       Specifies the key and button bindings  for  menus,  selections,
	       ''programmed  strings,'' etc.  The translations resource, which
	       provides much of xterm's configurability, is a feature of the X
	       Toolkit Intrinsics library (Xt).	 See the ACTIONS section.

       trimSelection (class TrimSelection)
	       If  you	set  highlightSelection, you can see the text which is
	       selected, including any trailing spaces.	 Clearing  the	screen
	       (or  a  line)  resets it to a state containing no spaces.  Some
	       lines may contain trailing spaces when  an  application	writes
	       them  to	 the screen.  However, you may not wish to paste lines
	       with trailing spaces.  If this resource	is  true,  xterm  will
	       trim  trailing spaces from text which is selected.  It does not
	       affect spaces which result in a wrapped line, nor will it  trim
	       the  trailing  newline  from  your  selection.	The default is
	       ''false.''

       underLine (class UnderLine)
	       This specifies whether or not text with the underline attribute
	       should be underlined.  It may be desirable to disable underlin-
	       ing when color is being used for the underline attribute.   The
	       default is ''true.''

       utf8 (class Utf8)
	       This  specifies	whether	 xterm will run in UTF-8 mode.	If you
	       set this resource, xterm also sets the wideChars resource as  a
	       side-effect.   The  resource  is	 an integer, expected to range
	       from 0 to 3:

	       0  UTF-8 mode is initially off.	The  command-line  option  +u8
		  sets the resource to this value.  Escape sequences for turn-
		  ing UTF-8 mode on/off are allowed.

	       1  UTF-8 mode is initially on.  Escape  sequences  for  turning
		  UTF-8 mode on/off are allowed.

	       2  The command-line option -u8 sets the resource to this value.
		  Escape sequences for turning UTF-8 mode on/off are  ignored.

	       3  This	is  the	 default value of the resource.	 It is changed
		  during  initialization  depending  on	 whether  the	locale
		  resource  was	 set,  to 0 or 2.  See the locale resource for
		  additional discussion of non-UTF-8 locales.

	       If you want to set the value of utf8,  it  should  be  in  this
	       range.	Other  nonzero	values	are treated the same as ''1'',
	       i.e., UTF-8 mode is initially  on,  and	escape	sequences  for
	       turning UTF-8 mode on/off are allowed.

       utf8Fonts (class Utf8Fonts)
	       See the discussion of the locale resource.

       utf8Latin1 (class Utf8Latin1)
	       If true, allow an ISO-8859-1 normal font to be combined with an
	       ISO-10646 font if the latter is given via the -fw option or its
	       corresponding resource value.  The default is ''false.''

       utf8Title (class Utf8Title)
	       Applications  can  set  xterm's	title  by  writing  a  control
	       sequence.  Normally this control	 sequence  follows  the	 VT220
	       convention,  which  encodes the string in ISO-8859-1 and allows
	       for an 8-bit string terminator.	If xterm is started in a UTF-8
	       locale,	it  translates	the ISO-8859-1 string to UTF-8 to work
	       with the X libraries which assume the string is UTF-8.

	       However, some users may wish to write a title string encoded in
	       UTF-8.	Set  this  resource to ''true'' to allow UTF-8 encoded
	       title strings.  That cancels the translation to UTF-8, allowing
	       UTF-8 strings to be displayed as is.

	       The default is ''false.''

       veryBoldColors (class VeryBoldColors)
	       Specifies whether to combine video attributes with colors spec-
	       ified by colorBD, colorBL, colorRV and colorUL.	 The  resource
	       value is the sum of values for each attribute:
		 1 for reverse,
		 2 for underline,
		 4 for bold and
		 8 for blink.

	       The default is ''0.''

       visualBell (class VisualBell)
	       Specifies whether or not a visible bell (i.e., flashing) should
	       be used instead of an audible bell when Control-G is  received.
	       The default is ''false.''

       visualBellDelay (class VisualBellDelay)
	       Number  of milliseconds to delay when displaying a visual bell.
	       Default is 100.	If set to zero, no visual bell	is  displayed.
	       This  is useful for very slow displays, e.g., an LCD display on
	       a laptop.

       vt100Graphics (class VT100Graphics)
	       This specifies whether xterm will interpret VT100 graphic char-
	       acter  escape  sequences	 while	in UTF-8 mode.	The default is
	       ''true'', to provide support for various legacy applications.

       wideBoldFont (class WideBoldFont)
	       This option specifies the font to be used for  displaying  bold
	       wide  text.  By default, it will attempt to use a font twice as
	       wide as the font that will be used to draw bold	text.	If  no
	       doublewidth font is found, it will improvise, by stretching the
	       bold font.

       wideChars (class WideChars)
	       Specifies if xterm should respond  to  control  sequences  that
	       process 16-bit characters.  The default is ''false.''

       wideFont (class WideFont)
	       This  option  specifies the font to be used for displaying wide
	       text.  By default, it will attempt to use a font twice as  wide
	       as  the font that will be used to draw normal text.  If no dou-
	       blewidth font is found, it will improvise,  by  stretching  the
	       normal font.

       ximFont (class XimFont)
	       This  option  specifies	the font to be used for displaying the
	       preedit string in the "OverTheSpot" input method.

	       In "OverTheSpot"	 preedit  type,	 the  preedit  (preconversion)
	       string  is  displayed at the position of the cursor.  It is the
	       XIM server's responsibility to display the preedit string.  The
	       XIM  client  must inform the XIM server of the cursor position.
	       For best results, the preedit string must be displayed  with  a
	       proper  font.   Therefore,  xterm informs the XIM server of the
	       proper font.  The font is be supplied  by  a  "fontset",	 whose
	       default	value  is "*".	This matches every font, the X library
	       automatically chooses fonts with proper charsets.  The  ximFont
	       resource is provided to override this default font setting.

       The  following  resources  are  specified as part of the tek4014 widget
       (class  Tek4014).   These   are	 specified   by	  patterns   such   as
       "XTerm.tek4014.NAME":

       ginTerminator (class GinTerminator)
	       Specifies  what character(s) should follow a GIN report or sta-
	       tus report.  The possibilities are  ''none,''  which  sends  no
	       terminating   characters,   ''CRonly,''	which  sends  CR,  and
	       ''CR&EOT,'' which sends	both  CR  and  EOT.   The  default  is
	       ''none.''

       height (class Height)
	       Specifies the height of the Tektronix window in pixels.

       initialFont (class InitialFont)
	       Specifies  which	 of the four Tektronix fonts to use initially.
	       Values are the  same  as	 for  the  set-tek-text	 action.   The
	       default is ''large.''

       width (class Width)
	       Specifies the width of the Tektronix window in pixels.

       The  following  resources  are  useful  when  specified	for the Athena
       Scrollbar widget:

       thickness (class Thickness)
	       Specifies the width in pixels of the scrollbar.

       background (class Background)
	       Specifies the color to use for the background of the scrollbar.

       foreground (class Foreground)
	       Specifies the color to use for the foreground of the scrollbar.
	       The ''thumb'' of the scrollbar is a simple checkerboard pattern
	       alternating pixels for foreground and background color.

POINTER USAGE
       Once  the  VT102 window is created, xterm allows you to select text and
       copy it within the same or other windows.

   SELECTION
       The selection functions are invoked when the pointer buttons  are  used
       with  no modifiers, and when they are used with the ''shift'' key.  The
       assignment of the functions described below to keys and buttons may  be
       changed through the resource database; see ACTIONS below.

       Pointer	button	one  (usually  left) is used to save text into the cut
       buffer.	Move the cursor to beginning of the text, and  then  hold  the
       button  down  while  moving  the	 cursor	 to  the end of the region and
       releasing the button.  The selected text is highlighted and is saved in
       the global cut buffer and made the PRIMARY selection when the button is
       released.  Normally (but see the discussion of on2Clicks, etc):

	      -	 Double-clicking selects by words.

	      -	 Triple-clicking selects by lines.

	      -	 Quadruple-clicking goes back to characters, etc.

       Multiple-click is determined by the time from button up to button down,
       so  you	can  change  the  selection unit in the middle of a selection.
       Logical words and lines selected by double- or triple-clicking may wrap
       across  more than one screen line if lines were wrapped by xterm itself
       rather than by the application running in the window.  If the  key/but-
       ton  bindings  specify  that  an	 X selection is to be made, xterm will
       leave the selected text highlighted for as long as it is the  selection
       owner.

       Pointer	button two (usually middle) 'types' (pastes) the text from the
       PRIMARY selection, if any, otherwise from the cut buffer, inserting  it
       as keyboard input.

       Pointer	button	three  (usually	 right) extends the current selection.
       (Without loss of generality, you can swap ''right'' and ''left'' every-
       where  in  the rest of this paragraph.)	If pressed while closer to the
       right edge of the selection than the  left,  it	extends/contracts  the
       right  edge  of	the selection.	If you contract the selection past the
       left edge of the selection, xterm assumes you  really  meant  the  left
       edge,  restores the original selection, then extends/contracts the left
       edge of the selection.  Extension starts in  the	 selection  unit  mode
       that  the  last selection or extension was performed in; you can multi-
       ple-click to cycle through them.

       By cutting and pasting pieces of text without trailing new  lines,  you
       can  take text from several places in different windows and form a com-
       mand to the shell, for example, or  take	 output	 from  a  program  and
       insert  it  into	 your favorite editor.	Since cut buffers are globally
       shared among different applications, you may regard each	 as  a	'file'
       whose contents you know.	 The terminal emulator and other text programs
       should be treating it as if it were a text  file,  i.e.,	 the  text  is
       delimited by new lines.

   SCROLLING
       The  scroll  region  displays the position and amount of text currently
       showing in the window (highlighted) relative  to	 the  amount  of  text
       actually saved.	As more text is saved (up to the maximum), the size of
       the highlighted area decreases.

       Clicking button one with the pointer in the  scroll  region  moves  the
       adjacent line to the top of the display window.

       Clicking	 button three moves the top line of the display window down to
       the pointer position.

       Clicking button two moves the display to a position in the  saved  text
       that corresponds to the pointer's position in the scrollbar.

   TEKTRONIX POINTER
       Unlike  the VT102 window, the Tektronix window does not allow the copy-
       ing of text.  It does allow Tektronix GIN mode, and in  this  mode  the
       cursor  will  change  from  an arrow to a cross.	 Pressing any key will
       send that key and the current coordinate of the cross cursor.  Pressing
       button  one,  two,  or three will return the letters 'l', 'm', and 'r',
       respectively.  If the 'shift' key is pressed when a pointer  button  is
       pressed, the corresponding upper case letter is sent.  To distinguish a
       pointer button from a key, the high bit of the character	 is  set  (but
       this  is	 bit is normally stripped unless the terminal mode is RAW; see
       tty(4) for details).

MENUS
       Xterm has four menus, named mainMenu, vtMenu,  fontMenu,	 and  tekMenu.
       Each  menu  pops	 up  under  the correct combinations of key and button
       presses.	 Each menu is divided into sections, separated by a horizontal
       line.   Some  menu  entries correspond to modes that can be altered.  A
       check mark appears next to a mode that is currently active.   Selecting
       one of these modes toggles its state.  Other menu entries are commands;
       selecting one of these performs the indicated function.

       All of the menu entries correspond to X actions.	 In  the  list	below,
       the menu label is shown followed by the action's name in parenthesis.

   Main Options
       The  xterm mainMenu pops up when the ''control'' key and pointer button
       one are pressed in a window.  This menu contains items  that  apply  to
       both the VT102 and Tektronix windows.  There are several sections:

       Commands for managing X events:

	      Toolbar
		     Clicking on the "Toolbar" menu entry hides the toolbar if
		     it is visible, and shows it if it is not.

	      Secure Keyboard (securekbd)
		     The Secure Keyboard mode is helpful when typing in	 pass-
		     words or other sensitive data in an unsecure environment;
		     see SECURITY below (but read the limitations  carefully).

	      Allow SendEvents (allowsends )
		     Specifies	whether or not synthetic key and button events
		     generated using the X protocol SendEvent  request	should
		     be	 interpreted  or  discarded.   This corresponds to the
		     allowSendEvents resource.

	      Redraw Window (redraw)
		     Forces the X display to repaint; useful in some  environ-
		     ments.

       Commands for capturing output:

	      Log to File (logging)
		     Captures  text sent to the screen in a logfile, as in the
		     -l logging option.

	      Print Window (print)
		     Sends the text of the current window to the program given
		     in the printerCommand resource.

	      Redirect to Printer (print-redir)
		     This  sets the printerControlMode to 0 or 2.  You can use
		     this to turn the printer on as if an application had sent
		     the  appropriate control sequence.	 It is also useful for
		     switching the printer off if an application turns	it  on
		     without resetting the print control mode.

       Modes for setting keyboard style:

	      8-Bit Controls (8-bit-control)
		     Enabled  for VT220 emulation, this controls whether xterm
		     will send 8-bit control sequences rather than using 7-bit
		     (ASCII)  controls,	 e.g.,	sending	 a  byte  in the range
		     128-159 rather than the escape character  followed	 by  a
		     second  byte.   Xterm  always  interprets	both 8-bit and
		     7-bit control sequences (see the document	Xterm  Control
		     Sequences).   This	 corresponds  to  the  eightBitControl
		     resource.

	      Backarrow Key (BS/DEL) (backarrow key)
		     Modifies the behavior of the  backarrow  key,  making  it
		     transmit  either  a backspace (8) or delete (127) charac-
		     ter.  This corresponds to the backarrowKey resource.

	      Alt/NumLock Modifiers (num-lock)
		     Controls the treatment of Alt- and NumLock-key modifiers.
		     This corresponds to the numLock resource.

	      Meta Sends Escape (meta-esc)
		     Controls whether Meta keys are converted into a two-char-
		     acter sequence with the character itself preceded by ESC.
		     This corresponds to the metaSendsEscape resource.

	      Delete is DEL (delete-is-del)
		     Controls  whether	the  Delete  key on the editing keypad
		     should send DEL (127) or the  VT220-style	Remove	escape
		     sequence.	 This corresponds to the deleteIsDEL resource.

	      Old Function-Keys (oldFunctionKeys)

	      HP Function-Keys (hpFunctionKeys)

	      SCO Function-Keys (scoFunctionKeys)

	      Sun Function-Keys (sunFunctionKeys)

	      VT220 Keyboard (sunKeyboard)
		     These act as a radio-button, selecting one style for  the
		     keyboard	layout.	  It  corresponds  to  more  than  one
		     resource setting: sunKeyboard, sunFunctionKeys,  scoFunc-
		     tionKeys and hpFunctionKeys ."

       Commands for process signalling:

	      Send STOP Signal (suspend)

	      Send CONT Signal (continue)

	      Send INT Signal (interrupt)

	      Send HUP Signal (hangup)

	      Send TERM Signal (terminate)

	      Send KILL Signal (kill)
		     These  send the SIGTSTP, SIGCONT, SIGINT, SIGHUP, SIGTERM
		     and SIGKILL signals respectively, to the process group of
		     the process running under xterm (usually the shell).  The
		     SIGCONT function is especially useful  if	the  user  has
		     accidentally typed CTRL-Z, suspending the process.

	      Quit (quit)
		     Stop  processing  X  events  except  to support the -hold
		     option, and then send a SIGHUP signal to the the  process
		     group  of	the  process  running under xterm (usually the
		     shell).


   VT Options
       The vtMenu sets various modes in the VT102 emulation, and is popped  up
       when  the  ''control''  key  and	 pointer button two are pressed in the
       VT102 window.

       VT102/VT220 Modes:

	      Enable Scrollbar (scrollbar)
		     Enable (or disable) the scrollbar.	 This  corresponds  to
		     the -sb option and the scrollBar resource.

	      Enable Jump Scroll (jumpscroll)
		     Enable  (or disable) jump scrolling.  This corresponds to
		     the -j option and the jumpScroll resource.

	      Enable Reverse Video (reversevideo)
		     Enable (or disable) reverse-video.	 This  corresponds  to
		     the -rv option and the reverseVideo resource.

	      Enable Auto Wraparound (autowrap)
		     Enable (or disable) auto-wraparound.  This corresponds to
		     the -aw option and the autoWrap resource.

	      Enable Reverse Wraparound (reversewrap)
		     Enable (or disable) reverse wraparound.  This corresponds
		     to the -rw option and the reverseWrap resource.

	      Enable Auto Linefeed (autolinefeed)
		     Enable (or disable) auto-linefeed.	 This is the VT102 NEL
		     function, which causes the emulator to  emit  a  linefeed
		     after  each  carriage  return.  There is no corresponding
		     command-line option or resource setting.

	      Enable Application Cursor Keys (appcursor)
		     Enable (or disable) application cursor keys.  This corre-
		     sponds  to	 the  appcursorDefault	resource.  There is no
		     corresponding command-line option.

	      Enable Application Keypad (appkeypad)
		     Enable (or disable) application keypad keys.  This corre-
		     sponds  to	 the  appkeypadDefault	resource.  There is no
		     corresponding command-line option.

	      Scroll to Bottom on Key Press (scrollkey)
		     Enable (or	 disable)  scrolling  to  the  bottom  of  the
		     scrolling	region on a keypress.  This corresponds to the
		     -sk option and the scrollKey resource.

	      Scroll to Bottom on Tty Output (scrollttyoutput)
		     Enable (or	 disable)  scrolling  to  the  bottom  of  the
		     scrolling region on output to the terminal..  This corre-
		     sponds  to	 the  -si  option  and	 the   scrollTtyOutput
		     resource.

	      Allow 80/132 Column Switching (allow132)
		     Enable (or disable) switching between 80 and 132 columns.
		     This  corresponds	to  the	 -132  option  and  the	  c132
		     resource.

	      Select to Clipboard (selectToClipboard)
		     Tell  xterm  whether  to use the PRIMARY or CLIPBOARD for
		     SELECT tokens in the  translations	 resource  which  maps
		     keyboard and mouse actions to select/paste actions.  This
		     corresponds to the selectToClipboard resource.  There  is
		     no corresponding command-line option.

	      Enable Visual Bell (visualbell)
		     Enable (or disable) visible bell (i.e., flashing) instead
		     of an audible bell.  This corresponds to the  -vb	option
		     and the visualBell resource.

	      Enable Pop on Bell (poponbell)
		     Enable  (or disable) raising of the window when Control-G
		     is received.  This corresponds to the -pop option and the
		     popOnBell resource.

	      Enable Margin Bell (marginbell)
		     Enable  (or  disable) a bell when the user types near the
		     right margin.  This corresponds to the -mb option and the
		     marginBell resource.

	      Enable Blinking Cursor (cursorblink)
		     Enable  (or  disable)  the blinking-cursor feature.  This
		     corresponds  to  the  -bc	option	and  the   cursorBlink
		     resource.	There is also an escape sequence (see the doc-
		     ument Xterm Control Sequences).  The menu entry  and  the
		     escape  sequence  states  are XOR'd: if both are enabled,
		     the cursor will not blink, if only one  is	 enabled,  the
		     cursor will blink.

	      Enable Alternate Screen Switching (titeInhibit)
		     Enable  (or  disable)  switching  between	the normal and
		     alternate screens.	 This corresponds to  the  titeInhibit
		     resource.	There is no corresponding command-line option.

	      Enable Active Icon (activeicon)
		     Enable (or disable) the active-icon feature.  This corre-
		     sponds to the -ai option and the activeIcon resource.

       VT102/VT220 Commands:

	      Do Soft Reset (softreset)
		     Reset  scroll  regions.  This can be convenient when some
		     program has  left	the  scroll  regions  set  incorrectly
		     (often a problem when using VMS or TOPS-20).  This corre-
		     sponds to the VT220 DECSTR control sequence.

	      Do Full Reset (hardreset)
		     The full reset entry will clear the screen, reset tabs to
		     every  eight  columns, and reset the terminal modes (such
		     as wrap and smooth scroll) to their initial  states  just
		     after  xterm  has	finished  processing  the command line
		     options.  This  corresponds  to  the  VT102  RIS  control
		     sequence,	with  a few obvious differences.  For example,
		     your session is not disconnected as a  real  VT102	 would
		     do.

	      Reset and Clear Saved Lines (clearsavedlines)
		     Perform a full reset, and also clear the saved lines.

       Commands for setting the current screen:

	      Show Tek Window (tekshow)
		     When enabled, pops the Tektronix 4014 window up (makes it
		     visible).	When disabled, hides the Tektronix  4014  win-
		     dow.

	      Switch to Tek Mode (tekmode)
		     When  enabled, pops the Tektronix 4014 window up if it is
		     not already visible, and switches	the  input  stream  to
		     that  window.   When  disabled,  hides the Tektronix 4014
		     window and switches input back to the VTxxx window.

	      Hide VT Window (vthide)
		     When enabled, hides the VTxxx window, shows the Tektronix
		     4014  window  if  it was not already visible and switches
		     the input stream to that window.	When  disabled,	 shows
		     the  VTxxx	 window, and switches the input stream to that
		     window.

	      Show Alternate Screen (altscreen)
		     When enabled, shows the alternate screen.	When disabled,
		     shows the normal screen.  Note that the normal screen may
		     have saved lines; the alternate screen does not.


   VT Fonts
       The fontMenu pops up when when the ''control'' key and  pointer	button
       three are pressed in a window.  It sets the font used in the VT102 win-
       dow, or modifies the way the font is specified or displayed.  There are
       three sections.

       The  first section allows you to select the font from a set of alterna-
       tives:

	      Default (fontdefault)
		     Set the font to the default,  i.e.,  that	given  by  the
		     *VT100.font resource.

	      Unreadable (font1)
		     Set  the font to that given by the *VT100.font1 resource.

	      Tiny (font2)
		     Set the font to that given by the *VT100.font2  resource.

	      Small (font3)
		     Set  the font to that given by the *VT100.font3 resource.

	      Medium (font4)
		     Set the font to that given by the *VT100.font4  resource.

	      Large (font5)
		     Set  the font to that given by the *VT100.font5 resource.

	      Huge (font6)
		     Set the font to that given by the *VT100.font6  resource.

	      Escape Sequence
		     This allows you to set the font last specified by the Set
		     Font escape sequence  (see	 the  document	Xterm  Control
		     Sequences).

	      Selection (fontsel)
		     This  allows  you	to  set the font specified the current
		     selection as a font name (if  the	PRIMARY	 selection  is
		     owned).

       The second section allows you to modify the way it is displayed:

	      Line-Drawing Characters (font-linedrawing)
		     When  set, tells xterm to draw its own line-drawing char-
		     acters.  Otherwise	 it  relies  on	 the  font  containing
		     these.  Compare to the forceBoxChars resource.

	      Doublesized Characters (font-doublesize)
		     When set, xterm may ask the font server to produce scaled
		     versions of the normal font, for VT102 double-size	 char-
		     acters.

       The third section allows you to modify the way it is specified:

	      TrueType Fonts (render-font)
		     If	 the  renderFont and corresponding resources were set,
		     this is a further control whether xterm will actually use
		     the Xft library calls to obtain a font.

	      UTF-8 (utf8-mode)
		     This  controls  whether  xterm  uses  UTF-8  encoding  of
		     input/output.  It is  useful  for	temporarily  switching
		     xterm  to display text from an application which does not
		     follow the locale settings.

   TEK Options
       The tekMenu sets various modes  in  the	Tektronix  emulation,  and  is
       popped  up  when the ''control'' key and pointer button two are pressed
       in the Tektronix window.	 The current font size is checked in the modes
       section of the menu.

	      Large Characters (tektextlarge)

	      #2 Size Characters (tektext2)

	      #3 Size Characters (tektext3)

	      Small Characters (tektextsmall)

       Commands:

	      PAGE (tekpage)
		     Clear the Tektronix window.

	      RESET (tekreset)

	      COPY (tekcopy)

       Windows:

	      Show VT Window (vtshow)

	      Switch to VT Mode (vtmode)

	      Hide Tek Window (tekhide)

SECURITY
       X  environments	differ in their security consciousness.	 Most servers,
       run under xdm, are capable of using a  ''magic  cookie''	 authorization
       scheme that can provide a reasonable level of security for many people.
       If your server is only using a host-based mechanism to  control	access
       to  the server (see xhost(1)), then if you enable access for a host and
       other users are also permitted to run clients on that same host, it  is
       possible	 that someone can run an application which uses the basic ser-
       vices of the X protocol to snoop on your activities,  potentially  cap-
       turing  a  transcript of everything you type at the keyboard.  Any pro-
       cess which has access to your X display can manipulate it in ways  that
       you  might not anticipate, even redirecting your keyboard to itself and
       sending events to your application's windows.  This is true  even  with
       the  ''magic  cookie'' authorization scheme.  While the allowSendEvents
       provides some protection against rogue applications tampering with your
       programs, guarding against a snooper is harder.

       The  possibility of an application spying on your keystrokes is of par-
       ticular concern when you want to type in a password or other  sensitive
       data.   The best solution to this problem is to use a better authoriza-
       tion mechanism than is provided by X.  Given all of  these  caveats,  a
       simple mechanism exists for protecting keyboard input in xterm.

       The  xterm  menu	 (see  MENUS  above)  contains a Secure Keyboard entry
       which, when enabled, attempts to ensure	that  all  keyboard  input  is
       directed only to xterm (using the GrabKeyboard protocol request).  When
       an application prompts you for a password (or  other  sensitive	data),
       you  can	 enable	 Secure Keyboard using the menu, type in the data, and
       then disable Secure Keyboard using the menu again.  This	 ensures  that
       you  know  which window is accepting your keystrokes.  It cannot ensure
       that there are no processes which have access to your  X	 display  that
       might be observing the keystrokes as well.

       Only  one X client at a time can grab the keyboard, so when you attempt
       to enable Secure Keyboard it may fail.  In this	case,  the  bell  will
       sound.	If the Secure Keyboard succeeds, the foreground and background
       colors will be exchanged (as if you selected the Reverse Video entry in
       the  Modes  menu);  they	 will  be exchanged again when you exit secure
       mode.  If the colors do not switch, then you should be very  suspicious
       that  you  are  being spoofed.  If the application you are running dis-
       plays a prompt before asking for the password, it is  safest  to	 enter
       secure mode before the prompt gets displayed, and to make sure that the
       prompt gets displayed correctly (in the new colors),  to	 minimize  the
       probability of spoofing.	 You can also bring up the menu again and make
       sure that a check mark appears next to the entry.

       Secure Keyboard mode will be disabled automatically if your xterm  win-
       dow  becomes  iconified	(or  otherwise unmapped), or if you start up a
       reparenting window manager (that places a title bar or other decoration
       around  the  window) while in Secure Keyboard mode.  (This is a feature
       of the X protocol not easily overcome.)	When this happens,  the	 fore-
       ground  and  background	colors will be switched back and the bell will
       sound in warning.

CHARACTER CLASSES
       Clicking the left mouse button twice in rapid succession (double-click-
       ing)  causes  all  characters  of  the same class (e.g., letters, white
       space, punctuation) to be selected as a ''word''.  Since different peo-
       ple  have  different preferences for what should be selected (for exam-
       ple, should filenames be selected as a whole or only the separate  sub-
       names),	the  default  mapping can be overridden through the use of the
       charClass (class CharClass) resource.

       This resource is a series of comma-separated of range:value pairs.  The
       range is either a single number or low-high in the range of 0 to 65535,
       corresponding to the code for the character or characters  to  be  set.
       The  value  is arbitrary, although the default table uses the character
       number of the first character occurring in the set.  When not in	 UTF-8
       mode, only the first 256 bytes of this table will be used.

       The default table starts as follows -

	   static int charClass[256] = {
	   /* NUL  SOH	STX  ETX  EOT  ENQ  ACK	 BEL */
	       32,   1,	  1,   1,   1,	 1,   1,   1,
	   /*  BS   HT	 NL   VT   NP	CR   SO	  SI */
		1,  32,	  1,   1,   1,	 1,   1,   1,
	   /* DLE  DC1	DC2  DC3  DC4  NAK  SYN	 ETB */
		1,   1,	  1,   1,   1,	 1,   1,   1,
	   /* CAN   EM	SUB  ESC   FS	GS   RS	  US */

       For  example,  the string ''33:48,37:48,45-47:48,38:48'' indicates that
       the exclamation mark, percent sign, dash, period, slash, and  ampersand
       characters  should  be  treated the same way as characters and numbers.
       This is useful for cutting and pasting electronic mailing addresses and
       filenames.

ACTIONS
       It  is  possible	 to  rebind  keys  (or sequences of keys) to arbitrary
       strings for input, by changing the translations resources for the vt100
       or  tek4014  widgets.   Changing	 the  translations resource for events
       other than key and button events is not expected, and will cause unpre-
       dictable	 behavior.   The following actions are provided for use within
       the vt100 or tek4014 translations resources:

       allow-send-events(on/off/toggle)
	       This action set or toggles the allowSendEvents resource and  is
	       also invoked by the allowsends entry in mainMenu.

       alt-sends-escape()
	       This action toggles the state of the eightBitInput resource.

       bell([percent])
	       This action rings the keyboard bell at the specified percentage
	       above or below the base volume.

       clear-saved-lines()
	       This action does hard-reset() (see below) and also  clears  the
	       history	of  lines saved off the top of the screen.  It is also
	       invoked from the clearsavedlines entry in vtMenu.   The	effect
	       is identical to a hardware reset (RIS) control sequence.

       create-menu(m/v/f/t)
	       This  action  creates one of the menus used by xterm, if it has
	       not been previously created.  The parameter values are the menu
	       names: mainMenu, vtMenu, fontMenu, tekMenu, respectively.

       dabbrev-expand()
	       Expands	the  word  before cursor by searching in the preceding
	       text on the screen and  in  the	scrollback  buffer  for	 words
	       starting	 with  that  abbreviation.  Repeating dabbrev-expand()
	       several times in sequence searches for an alternative expansion
	       by looking farther back.	 Lack of more matches is signaled by a
	       beep().	Attempts to expand an empty word (i.e., when cursor is
	       preceded	 by  a	space)	yield successively all previous words.
	       Consecutive identical expansions are ignored.  The word here is
	       defined	as a sequence of non-whitespace characters.  This fea-
	       ture partially emulates the behavior of 'dynamic	 abbreviation'
	       expansion  in  Emacs  (bound there to M-/).  Here is a resource
	       setting for xterm which will do the same thing:

		   *VT100*translations:	   #override \n\
			Meta <KeyPress> /:dabbrev-expand()


       deiconify()
	       Changes the window state back to normal, if it was iconified.

       delete-is-del()
	       This action toggles the state of the deleteIsDEL resource.

       dired-button()
	       Handles a button event (other than press and release) by	 echo-
	       ing  the	 event's position (i.e., character line and column) in
	       the following format:

		       ^X ESC G <line+' '> <col+' '>

       iconify()
	       Iconifies the window.

       hard-reset()
	       This action resets the scrolling region, tabs, window size, and
	       cursor keys and clears the screen.  It is also invoked from the
	       hardreset entry in vtMenu.

       ignore()
	       This action ignores the event but checks	 for  special  pointer
	       position escape sequences.

       insert()
	       This action inserts the character or string associated with the
	       key that was pressed.

       insert-eight-bit()
	       This action inserts an eight-bit (Meta) version of the  charac-
	       ter  or	string associated with the key that was pressed.  This
	       only applies to single-byte values.  The exact  action  depends
	       on  the	value  of  the	metaSendsEscape	 and the eightBitInput
	       resources.  The metaSendsEscape resource is tested first.

	       The term "eight-bit" is misleading: xterm checks if  the	 key's
	       value  is  less	than 128.  If so, xterm adds 128 to the value,
	       setting its eighth bit.	Otherwise  xterm  sends	 an  ESC  byte
	       before  the key.	 In other applications' documentation, that is
	       referred to as a "meta key".

       insert-selection(sourcename [, ...])
	       This action inserts the string found in the selection  or  cut-
	       buffer  indicated  by  sourcename.   Sources are checked in the
	       order given (case is significant) until	one  is	 found.	  Com-
	       monly-used  selections  include:	 PRIMARY, SECONDARY, and CLIP-
	       BOARD.  Cut buffers are	typically  named  CUT_BUFFER0  through
	       CUT_BUFFER7.

       insert-seven-bit()
	       This  action  is a synonym for insert() The term "seven-bit" is
	       misleading: it only implies that xterm does not try to add  128
	       to the key's value as in insert-eight-bit().

       interpret(control-sequence)
	       Interpret  the  given  control  sequence locally, i.e., without
	       passing it to the host.	This works by  inserting  the  control
	       sequence	 at  the front of the input buffer.  Use "\" to escape
	       octal digits in the string.  Xt does not allow  you  to	put  a
	       null character (i.e., "\000") in the string.

       keymap(name)
	       This  action  dynamically defines a new translation table whose
	       resource name is name with the suffix Keymap (case is  signifi-
	       cant).	The name None restores the original translation table.

       larger-vt-font()
	       Set the font to the next larger one, based on the  font	dimen-
	       sions.  See also set-vt-font().

       load-vt-fonts(name[,class])
	       Load fontnames from the given subresource name and class.  That
	       is, load the "*VT100.name.font", resource as "*VT100.font" etc.
	       If no name is given, the original set of fontnames is restored.

	       Unlike set-vt-font(), this does	not  affect  the  escape-  and
	       select-fonts, since those are not based on resource values.  It
	       does affect the fonts loosely organized under  the  ''Default''
	       menu entry: font, boldFont, wideFont and wideBoldFont.

       maximize()
	       Resizes the window to fill the screen.

       meta-sends-escape()
	       This  action toggles the state of the metaSendsEscape resource.

       popup-menu(menuname)
	       This action displays the specified  popup  menu.	  Valid	 names
	       (case is significant) include:  mainMenu, vtMenu, fontMenu, and
	       tekMenu.

       print() This action prints the window and is also invoked by the	 print
	       entry in mainMenu.

       print-redir()
	       This  action  toggles  the  printerControlMode between 0 and 2.
	       The corresponding popup menu entry is useful for switching  the
	       printer off if you happen to change your mind after deciding to
	       print random binary files on the terminal.

       quit()  This action sends a SIGHUP to the subprogram and exits.	It  is
	       also invoked by the quit entry in mainMenu.

       redraw()
	       This  action  redraws  the  window  and	is also invoked by the
	       redraw entry in mainMenu.

       restore()
	       Restores the window to the size before it was last maximized.

       scroll-back(count [,units [,mouse] ])
	       This action scrolls the text window backward so that text  that
	       had  previously scrolled off the top of the screen is now visi-
	       ble.

	       The count argument indicates the number of units (which may  be
	       page, halfpage, pixel, or line) by which to scroll.

	       An  adjustment can be specified for these values by appending a
	       "+" or "-" sign followed by a number, e.g., page-2 to specify 2
	       lines less than a page.

	       If  the	third  parameter mouse is given, the action is ignored
	       when mouse reporting is enabled.

       scroll-forw(count [,units [,mouse] ])
	       This action is similar to scroll-back except that it scrolls in
	       the other direction.

       secure()
	       This  action  toggles the Secure Keyboard mode described in the
	       section named SECURITY, and is invoked from the securekbd entry
	       in mainMenu.

       select-cursor-end(destname [, ...])
	       This  action  is similar to select-end except that it should be
	       used with select-cursor-start.

       select-cursor-start()
	       This action is similar to select-start except  that  it	begins
	       the selection at the current text cursor position.

       select-end(destname [, ...])
	       This  action  puts  the currently selected text into all of the
	       selections or cutbuffers specified by destname.

       select-extend()
	       This action tracks the pointer and extends the  selection.   It
	       should only be bound to Motion events.

       select-set()
	       This  action stores text that corresponds to the current selec-
	       tion, without affecting the selection mode.

       select-start()
	       This action begins text selection at the current pointer	 loca-
	       tion.  See the section on POINTER USAGE for information on mak-
	       ing selections.

       send-signal(signame)
	       This action sends the signal named by signame to the xterm sub-
	       process	(the  shell  or	 program specified with the -e command
	       line option) and is also	 invoked  by  the  suspend,  continue,
	       interrupt,  hangup,  terminate,	and  kill entries in mainMenu.
	       Allowable signal names are (case is not significant): tstp  (if
	       supported  by  the  operating  system), suspend (same as tstp),
	       cont (if supported by the operating system),  int,  hup,	 term,
	       quit, alrm, alarm (same as alrm) and kill.

       set-toolbar(on/off/toggle)
	       This  action toggles the toolbar feature and is also invoked by
	       the toolbar entry in mainMenu.

       set-utf8-mode(on/off/toggle)
	       This action toggles the utf8 resource and is  also  invoked  by
	       the utf8-mode entry in fontMenu.

       set-utf8-title(on/off/toggle)
	       This  action toggles the utf8Title resource and is also invoked
	       by the utf8-title entry in fontMenu.

       set-visibility(vt/tek,on/off/toggle)
	       This action controls whether or not the vt or tek  windows  are
	       visible.	  It  is  also	invoked	 from  the  tekshow and vthide
	       entries in vtMenu and the vtshow and tekhide  entries  in  tek-
	       Menu.

       set-visual-bell(on/off/toggle)
	       This action toggles the visualBell resource and is also invoked
	       by the visualbell entry in vtMenu.

       set-vt-font(d/1/2/3/4/5/6/e/s [,normalfont [, boldfont]])
	       This action sets the font or fonts currently being used in  the
	       VT102  window.	The  first argument is a single character that
	       specifies the font to be used:

	       d or D indicate the default font (the font initially used  when
		      xterm was started),

	       1  through  6 indicate the fonts specified by the font1 through
		      font6 resources,

	       e or E indicate the normal and bold fonts that  have  been  set
		      through  escape  codes  (or  specified as the second and
		      third action arguments, respectively), and

	       s or S indicate the font selection (as made by programs such as
		      xfontsel(1)) indicated by the second action argument.

	       If  xterm  is  configured  to support wide characters, an addi-
	       tional two optional parameters are recognized for the  e	 argu-
	       ment: wide font and wide bold font.

       smaller-vt-font()
	       Set  the font to the next smaller one, based on the font dimen-
	       sions.  See also set-vt-font().

       soft-reset()
	       This action resets the scrolling region	and  is	 also  invoked
	       from the softreset entry in vtMenu.  The effect is identical to
	       a soft reset (DECSTR) control sequence.

       start-extend()
	       This action is similar to select-start except that  the	selec-
	       tion is extended to the current pointer location.

       start-cursor-extend()
	       This  action is similar to select-extend except that the selec-
	       tion is extended to the current text cursor position.

       string(string)
	       This action inserts the specified text string as if it had been
	       typed.	Quotation  is necessary if the string contains whites-
	       pace or non-alphanumeric characters.  If	 the  string  argument
	       begins  with  the characters ''0x'', it is interpreted as a hex
	       character constant.

       tek-copy()
	       This action copies the escape codes used to generate  the  cur-
	       rent  window contents to a file in the current directory begin-
	       ning with the name COPY.	 It is also invoked from  the  tekcopy
	       entry in tekMenu.

       tek-page()
	       This  action clears the Tektronix window and is also invoked by
	       the tekpage entry in tekMenu.

       tek-reset()
	       This action resets the Tektronix window and is also invoked  by
	       the tekreset entry in tekMenu.

       vi-button()
	       Handles	a button event (other than press and release) by echo-
	       ing a control sequence computed from the event's line number in
	       the screen relative to the current line:

		       ESC ^P
	       or
		       ESC ^N

	       according  to whether the event is before, or after the current
	       line, respectively.  The ^N (or ^P) is repeated once  for  each
	       line that the event differs from the current line.  The control
	       sequence is omitted altogether if the button event  is  on  the
	       current line.

       visual-bell()
	       This action flashes the window quickly.

       The Tektronix window also has the following action:

       gin-press(l/L/m/M/r/R)
	       This action sends the indicated graphics input code.

       The default bindings in the VT102 window use the SELECT token, which is
       set by the selectToClipboard resource:

       Here is an example which uses shifted select/paste to copy to the clip-
       board,  and  unshifted select/paste for the primary selection.  In each
       case, a (different) cut buffer is  also	a  target  or  source  of  the
       select/paste  operation.	 It is important to remember however, that cut
       buffers store data in ISO-8859-1 encoding, while selections  can	 store
       data  in	 a  variety  of	 formats  and encodings.  While xterm owns the
       selection, it highlights it.  When it loses the selection,  it  removes
       the  corresponding  highlight.  But you can still paste from the corre-
       sponding cut buffer.

	   *VT100*translations:	   #override \n\
	       ~Shift~Ctrl<Btn2Up>: insert-selection(PRIMARY, CUT_BUFFER0) \n\
	       Shift~Ctrl<Btn2Up>:  insert-selection(CLIPBOARD, CUT_BUFFER1) \n\
	       ~Shift<BtnUp>:	    select-end(PRIMARY, CUT_BUFFER0) \n\
	       Shift<BtnUp>:	    select-end(CLIPBOARD, CUT_BUFFER1)


       Below is a sample how of the keymap() action is	used  to  add  special
       keys for entering commonly-typed works:

	   *VT100.Translations: #override <Key>F13: keymap(dbx)
	   *VT100.dbxKeymap.translations: \
		<Key>F14: keymap(None) \n\
		<Key>F17: string("next") string(0x0d) \n\
		<Key>F18: string("step") string(0x0d) \n\
		<Key>F19: string("continue") string(0x0d) \n\
		<Key>F20: string("print ") insert-selection(PRIMARY, CUT_BUFFER0)


CONTROL SEQUENCES AND KEYBOARD
       The  Xterm Control Sequences document lists the control sequences which
       an application can send xterm to make it	 perform  various  operations.
       Most  of these operations are standardized, from either the DEC or Tek-
       tronix terminals, or from more widely used standards such as ISO	 6429.

ENVIRONMENT
       Xterm sets several environment variables:

       DISPLAY
	    is	the  display name, pointing to the X server (see DISPLAY NAMES
	    in X(el5_4.1-root-mockbuild/usr/share/man/xterm.1)).

       TERM is set according to the termcap (or terminfo) entry	 which	it  is
	    using as a reference.

       WINDOWID
	    is set to the X window id number of the xterm window.

       XTERM_SHELL
	    is	set  to the pathname of the program which is invoked.  Usually
	    that is a shell program, e.g., /bin/sh.  Since it is not necessar-
	    ily a shell program however, it is distinct from ''SHELL''.

       XTERM_VERSION
	    is	set  to	 the string displayed by the -version option.  That is
	    normally an identifier for the X Window libraries  used  to	 build
	    xterm, followed by xterm's patch number in parenthesis.  The patch
	    number is  also  part  of  the  response  to  a  Secondary	Device
	    Attributes (DA) control sequence (see Xterm Control Sequences).

       Depending  on your system configuration, xterm may also set the follow-
       ing:

       COLUMNS
	    the width of the xterm in characters (cf: "stty columns").

       HOME when xterm is configured to update utmp.

       LINES
	    the height of the xterm in characters (cf: "stty rows").

       LOGNAME
	    when xterm is configured to update utmp.

       SHELL
	    when xterm is configured to update utmp.  It is also  set  if  you
	    provide the shell name as the optional parameter.

       TERMCAP
	    the	 contents  of  the  termcap entry corresponding to $TERM, with
	    lines and columns values substituted for the  actual  size	window
	    you have created.

       TERMINFO
	    may	 be defined to a nonstandard location in the configure script.

FILES
       The actual pathnames given may differ on your system.

       /etc/utmp
	    the system logfile, which records user logins.

       /etc/wtmp
	    the system logfile, which records user logins and logouts.

       /usr/share/X11/app-defaults/XTerm
	    the xterm default application resources.

       /usr/share/X11/app-defaults/XTerm-color
	    the xterm color application resources.  If your  display  supports
	    color, use this
		      *customization: -color
	    in	your  .Xdefaults  file to automatically use this resource file
	    rather than /usr/share/X11/app-defaults/XTerm.  If you do  not  do
	    this,  xterm  uses	its  compiled-in default resource settings for
	    colors.

ERROR MESSAGES
       Most of the fatal error messages from xterm use the following format:
	      xterm: Error XXX, errno YYY: ZZZ
       The XXX codes (which are used by xterm as  its  exit-code)  are	listed
       below, with a brief explanation.

       1    is	used  for  miscellaneous errors, usually accompanied by a spe-
	    cific message,

BUGS
       Large pastes do not work on some systems.  This is not a bug in	xterm;
       it  is  a  bug  in  the pseudo terminal driver of those systems.	 xterm
       feeds large pastes to the pty only as fast as the pty will accept data,
       but  some  pty  drivers do not return enough information to know if the
       write has succeeded.

       Many of the options are not resettable after xterm starts.

       This program still needs to be rewritten.  It should be split into very
       modular	sections, with the various emulators being completely separate
       widgets that do not know about each other.  Ideally, you'd like	to  be
       able  to	 pick and choose emulator widgets and stick them into a single
       control widget.

       There needs to be a dialog box to allow entry  of  the  Tek  COPY  file
       name.
