/NEXT="hot-key-defintion"

   This qualifier is used to define a hot-key sequence which causes PEEK
   to stop watching the current target and start watching the next target
   (if there is another target which matches the specification(s) given).

   If there is no next targets to watch, the NEXT hot-key performs an
   END_WATCH.

   The default hot-key value is taken from the logical WATCHER$NEXT.

   Example:

         $ PEEK/NEXT="<CTRL-P>N" GROUP1*
     or
         $ DEFINE WATCHER$NEXT "<CTRL-P>N"
         $ PEEK GROUP1*

   In either case when the watcher presses Control-P followed by the
   letter N, PEEK will stop watching the current user and try to watch
   a next user, if any.
