Syntax:  SHOW KEY user_key_name_wild

  Displays the definitions of the specified key(s).

  This command displays the key definitions bound to the specified set
  of keys, both the default key bindings and key bindings you create
  with the DEFINE KEY command.  If you do not specify a key name, LSE
  prompts for one.

  If you specify a keyname, LSE displays full information about that
  key.  If you specify a wildcard keyname, LSE displays a brief list of
  all keys matching that name.  Use Ctrl/F (forward) and Ctrl/B
  (reverse) to navigate through the list of keys.  Ctrl/E (expand) lets
  you display full information on any one key.  The COLLAPSE command
  reverts back to the brief display.
