SELECT ALL
  Selects all of the current buffer---regardless of your position---so you
  can perform an editing operation on the selection.
  Key:   DECwindows
         -----------
         M1CLICK5
         CTRL-/
  Steps:
     1.  Use the SELECT ALL command, or click M1 five times on DECwindows.
         The entire buffer is highlighted in reverse video. You can press
         CTRL-/ which is a Motif function key, and is enabled by default.
     2.  To edit the selection, use a command or key that works
         on a select range---see help on Ranges And Boxes.
  Usage notes:
  o  To cancel the selection, do any of the following:
        *  Use the RESET command (for example, press GOLD-SELECT).
        *  Repeat SELECT or BOX SELECT (for example, press the SELECT key).
        *  Click M1 once (which also repositions the cursor).
  o  If you use SELECT ALL, you cannot use the following:
        Box editing (such as BOX COPY or BOX CUT)
        Pending delete
        FIND SELECTED
        OPEN SELECTED
  o  On DECwindows, if you select text, the pop-up menu (displayed by
     holding down M2) contains COPY, CUT, FILL RANGE, case changes, and
     other commands for editing a selection. See help on Menus.
