Syntax:  SHOW TOKEN token_name_wild defined_language

  Displays the definitions and characteristics of one or more tokens.

  If you specify a token name, LSE displays all the attributes
  associated with that token.  If you specify a wildcard token name,
  LSE displays a list with brief information about each matching token.

  You can navigate through the list using Ctrl/F (forward) and Ctrl/B
  (reverse).  Ctrl/E (expand) lets you dislay full information about
  the indicated placeholder.  The COLLAPSE command reverts back to the
  brief display.
