       xev - print contents of X events

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

       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.

       -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 window.

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