Certain keys have four characters.  KEYBOARD I makes the left-handed pair .
   available, KEYBOARD II makes the right-hand pair available.

While holding [USE FRONT], press [KEYBOARD I/II] to switch back and forth

The "I/II" signs on the ruler indicate which keyboard you are using.

[UNDO] restores the keyboard to the way it was before you used the command.
