Each softkey can have a unique definition for each of four menus (SYSTEM, USER1, USER2, and USER3). Press Shift+F11 (INCR LABELS) to cycle through each of the four menus, or F12 for SYSTEM, or Shift+F12 for USER1. F11 toggles the menu on and off. These same operations can be executed with the program statements: SYSTEM KEYS, USER n KEYS, and KEY LABELS ON/OFF respectively. Also, pressing Alt with a function key forces SYSTEM key function definitions to override any active USER Menu.
KBD CMODE OFF selects an alternate softkey menu style which maps keyboard Function keys F1 to F8 to the respective softkeys K1-K8.

KBD CMODE ON selects a two-rows of 5 softkeys style menu which maps F1-F10 to softkeys K0-K9 (un-shifted) and shifted F1-F10 to K10-K19 (as per legacy HP Basic). However, softkey label numbers still refer to the keyboard function key numbers. And, as above, pressing Alt with a function key causes SYSTEM menu definitions to supersede any active USER menu.
