The KeyCapture subcommands are:

   ATTACH        - Attach to another process in you job.
   EXIT          - Exit interactive KeyCapture prompting.
   FORMAT        - Format a log file.
   HELP          - Access on-line KeyCapture help.
   LICENSE       - Enter Product Authorization Key.
   NODE_NAME_CHANGE - Update licensed nodename after a nodename change.
   NOTRACK       - End KeyCapture logging.
   QUIT          - Exit interactive KeyCapture prompting.
   RT_ENABLE     - (VAX-Only) Enable VAX KeyCapture on an RTA unit.
   SHOW          - Show various KeyCapture data.
   SHUTDOWN      - Shut down KeyCapture - Only use from KCAP_SHUTDOWN.COM.
   SPAWN         - Spawn a subprocess.
   TRACK         - Start KeyCapture logging.

   As shipped, subcommands may be used as verbs during interactive
   KeyCapture command prompting (e.g. KCAP> TRACK), but subcommands
   must be entered as qualifiers when used as part of a single-line
   DCL command (e.g. $ KCAP/TRACK). This default behavior can be
   changed. See the KeyCapture Commands Subtopic: /COMMAND_MODE.
