NAME
     xev - print contents of X events

SYNOPSIS
     /usr/bin/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 it
     being moved, resized, typed in, clicked in, etc.).  You  can
     also attach it to an existing window.  It is useful for see-
     ing what causes events to occur and to display the  informa-
     tion  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  win-
             dow.

     -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  current  window
             obscures  other  windows.  Save  unders   are   only
             advisory, and are normally set for popup dialogs and
             other transient 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 video.
