xev - print contents of X events

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

Xev creates a window and then asks the X server to send it
events whenever anything happens to the window (such as
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.

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

-geometry geom
This option specifies the size and/or location of
the window.

-bw pixels
This option specifies the border width for the

-bs {NotUseful,WhenMapped,Always}
This option specifies what kind of backing store
to give the window. The default is NotUseful.

-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.

-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.
