Syntax:  SET MENU MNEMONICS boolean

  Sets the menu mnemonics on or off.

  The parameter value off allows all Alt key combinations to be used,
  since mnemonics consume some Alt key combinations.  The new menu
  mnemonics state will not take effect until you enter a SAVE SECTION
  command and invoke LSE with that new section file.
