       xev - print contents of X events


       xev   [-display   displayname]   [-geometry  geom]  [-bw  pixels]  [-bs
       {NotUseful,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
       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 seeing what causes events  to  occur
       and  to  display the information that they contain; it is essentially a
       debugging and development tool, and should  not  be  needed  in  normal


       -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
               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

       -event event_mask
               Select which events to  display.   The  -event  option  can  be
               specified  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.
