WPS Scroll Backup

  Scrolls vertically, moving back until you halt scrolling or until reach
  the top of the buffer.

  Steps:

     1.  Press the WPS Scroll Backup key (GOLD-KP1).

     2.  To halt scrolling, press any key.  The normal function of that key
         is then executed.  Typically, you press the WPS Halt key (GOLD-`).

  Usage notes:

  o  If the cursor is bound, it moves to the corresponding position on the
     line where you halt the scrolling or to the top of buffer.  (Setting
     the WPS keypad automatically enables bound cursor.)

  o  If the cursor is free, it moves up in the same column, regardless of
     whether text is there or not.  Conceptually, the cursor remains in the
     same position on the screen while the buffer scrolls up.
