HOW TO USE PREDICTIVE TEXT (abc mode)
Predictive text allows words to be entered more efficiently using a single key
press for each letter, as opposed to multiple key presses in abc text mode.
To change from multi-tap to predictive text press # to view the entry options,
then select En. This will activate English predictive text
Predictive text uses a built-in dictionary to match possible words against your
key presses and reduce the number of key presses required for text entry.
Handy Hint:
In predictive text mode, when a word is underlined press the # key to raise
the case. Eg. dave > Dave.
You may find that there are multiple valid words that can use the same key
press. If this is the case a dropdown list will appear, simply use the Arrow
Keys to choose from available words to the one that you want and press OK
to confirm
