25-Key Numeric Keyboard
The following graphic displays the 25-key numeric keyboard.
Alpha Mode
The 25-key keyboard defaults to numeric mode. Numeric mode is when you type numbers with the number keys. Alpha mode is
when you type letters or characters with the number keys.
To toggle between numeric and alpha modes, double-tap the Blue modifier key. There are alpha indicators on the number buttons
that specify the letters or characters that will be typed when you press that key in alpha mode.
Please note that when typing in alpha mode, you must use the same multi-press method you would use when typing letters on
a phone keypad. Each key press will type the next letter in the sequence as displayed by the alpha indicator.
You can still use the Blue modifier key for regular Blue key combinations; just press and hold Blue modifier key with the next key
in the combination. For details,
see Blue Key Combinations on page 6-8.
Caps Lock Key in Alpha Mode
After you double-tap the Blue modifier key to switch the alpha mode and begin typing, letters appear in upper case by default.
To toggle between upper and lower cases in alpha mode, tap the Caps Lock key once.
