    0x3f  The x server interprets this keycode as a middle button

    NOTES: There should be a better way of handling mice in the X server.
463 
    The MOUSE_ESCAPE code (0x7e) should be followed by three bytes instead
464 
    of two.  The three mouse buttons should then, in the X server, be read
465 
    as the high-bits of all three bytes.  The x and y motions can still be
466 
    in the first two bytes.  Maybe I'll do this...
