XEV(1)

NAME
       xev - print contents of X events

SYNOPSIS
       xev  [-display  displayname] [-geometry geom] [-bw pixels]
       [-bs {NotUseful,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
       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.

OPTIONS
       -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
               window.

       -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.
