       xev - print contents of X events

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

       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.

       -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

       -event event_mask
	       Select which events to display.	The -event option can be spec-
	       ified  multiple times to	select multiple	types of events.  When
	       not specified, all events are selected.	Available event	masks:
	       keyboard	 mouse	expose visibility structure substructure focus
	       property	colormap owner_grab_button randr button

	       This option prints the program version and exits.
