NAME
       xev - print contents of X events

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

DESCRIPTION
       Xev creates a window and then asks the X	 server	 to  send  it  events
       whenever	 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
       debugging  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.

       -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 win-
	       dow.

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