Alpha Primary Keypad
The Alpha Primary keypad produces the 26-character alphabet (A-Z, both lowercase and uppercase), numbers
(0-9), and assorted characters. The keypad is color-coded to indicate which modifier key to press to produce a
particular character or action. The keypad default is lowercase alpha characters. See Table B-1 for key and button
descriptions and Table B-3 on page B-6 for the keypad’s special functions.
