SHOW KEY
  Shows the current definition of a key you specify. You can type the key
  name on the command line or let EVE prompt you to press the key to be
  shown.
  Example:
     The following command shows the definition of GOLD-KP8 when you are
     using the EDT keypad. EVE displays the definition in the message window
     (bottom line of the screen).
        Command: SHOW KEY gold-kp8
        GOLD-KP8 is defined as 'fill' in the EDT keypad.
  Usage notes:
  o  In specifying key combinations, use a dash, slash, or underscore as a
     delimiter in the key name. For more information, see help on Names For
     Keys.
  o  If you do not type the key name on the command line, SHOW KEY prompts
     you to press the key you want to know about:
        Function key ............. such as F20, PF3, KP0, or ENTER
        GOLD key sequence ........ such as GOLD-A or GOLD-PF3
        Control key .............. such as CTRL/A or GOLD-CTRL/A
        Shifted function key ..... such as SHIFT/F14 (DECwindows only)
        ALT key combination ...... such as ALT/Z     (DECwindows only)
        Mouse button ............. such as M2CLICK   (DECwindows only)
  o  If the specified key is defined for a learn sequence, SHOW KEY tells
     you the key is defined as "Sequence."
