; LX-MENU Simulates a LETTRIX menu key-press.
;
; If you want to change a LETTRIX setting from within a batch file, you can use
; the LX-MENU command followed by a single letter. For example,
;
; LX-MENU l turns LETTRIX off, and
; LX-MENU L turns LETTRIX on again.
; LX-MENU = causes LETTRIX to ignore \ commands.
; LX-MENU L causes LETTRIX to acknowledge \ commands again.
