NAME
       xev - print contents of X events

SYNOPSIS
       xev  [-display displayname] [-geometry geom] [-bw pixels] [-bs {NotUse-
       ful,WhenMapped,Always}] [-id  windowid]	[-root]	 [-s]  [-name  string]
       [-rv]

DESCRIPTION
       Xev creates a window and then asks the X server to send it events when-
       ever anything happens to the window (such as it being  moved,  resized,
       typed  in,  clicked  in,	 etc.).	 You can also attach it to an existing
       window.	It is useful for seeing what causes events  to	occur  and  to
       display	the  information that they contain; it is essentially a debug-
       ging and development tool, and should not be needed in normal usage.

OPTIONS
       -display display
	       This option specifies the X server to contact.

       -geometry geom
	       This option specifies the size and/or location of  the  window,
	       if a window is to be created.

       -bw pixels
	       This option specifies the border width for the window.

       -bs {NotUseful,WhenMapped,Always}
	       This  option  specifies	what kind of backing store to give the
	       window.	The default is NotUseful. Backing store refers to  the
	       the  pixels  saved  off-screen  when the X server maintains the
	       contents of a window; NotUseful means that the xev process will
	       redraw its contents itself, as necessary.

       -id windowid
	       This  option specifies that the window with the given id should
	       be monitored, instead of creating a new window.

       -root   This option specifies that the root window should be monitored,
	       instead of creating a new window.

       -s      This option specifies that save-unders should be enabled on the
	       window. Save unders are similar	to  backing  store,  but  they
	       refer  rather  to the saving of pixels off-screen when the cur-
	       rent window obscures other windows. Save unders are only	 advi-
	       sory,  and  are	normally set for popup dialogs and other tran-
	       sient windows.

       -name string
	       This option specifies the name to assign to the created window.

       -rv     This option specifies that the  window  should  be  in  reverse
	       video.
