Overlay
Type the characters and do the operations printed on the
overlay when the keyboard is in function [FUNC] mode or
alternate [ALT] mode. Figure 2-1 shows that the [FUNC]
key is to the left and the [ALT] key is to the right. Charac-
ters printed on the overlay have the same relative relation-
ship; the operation above a key and to the left (black letter-
ing) indicates function mode, and the character or operation
above a key and to the right (yellow lettering) indicates al-
ternate mode.
You can also use the cursor control key in the upper right
corner of the keyboard in combination with the function and
alternate modes.
Radio terminal keys and their colors are listed in the follow-
ing chart.
