The toggle key for Alphabet / Numeral input.
When the system is in alpha-mode, a small icon will be shown in the lower right
corner of the display. For the 24-key keyboard, each numeric key can be used to
generate one of the three capital letters located on that number key. For example,
numeral 2 can be used to produce A, B, or C. Pressing the same key twice within
one second, will produce the letter B. Pressing the same key without halting
longer than one second, will allow the user to toggle through the three letters.
When the key has been depressed for longer than one second or another key has
been pressed, the unit will send the real key code to the application program.
The function key.
This key cannot be activated alone, it must be pressed with one of the numeric
keys at the same time. For example, FN + 1 generates function #1, FN + 2
generates function #2, etc (up to 9 functions). Also, this key can be combined
with the UP/DOWN arrow keys to adjust the contrast of the LCD. And when this
key is combined with the ENTER key, it will turn ON/OFF the backlight.
