Pressed Undefined Key

  The key you pressed is undefined or unknown for HELP.

  To define the key, use DEFINE KEY or LEARN. Also, some other commands may
  define the key, such as SET KEYPAD EDT, SET KEYPAD WPS, or SET FUNCTION
  KEYS DECWINDOWS.

  If you use the DEFINE_KEY built-in or EVE$DEFINE_KEY procedure, such as in
  a command file, you should include, after the key name, the name of the
  help topic to display for that key and the name of the keymap, as in the
  following example:

     EVE$DEFINE_KEY ("EVE_GO_TO ('')", CTRL_G_KEY, "GO_TO", EVE$X_USER_KEYS);
