123 Mode
123 mode lets you use keypad number keys to enter
numbers into a text message, event, or e-mail address
without going through repeated key presses as with
ABC mode.
T9 Word Text Entry Mode
T9 Word recognizes a commonly used word that is
represented by a sequence of number key presses and
inserts that word into your message. (For example,
entering ‘8378’ would insert ‘test’ into your message.)
Using T9 Word is much faster than the more traditional
text input method (ABC mode) and requires only one
press of a key per letter of the word that you’re
entering. (For example, in ABC mode, you would have
to enter ‘83377778’ for ‘test’ instead of entering ‘8378’
for ‘test’ as in T9 Word mode.)
Note: See “Using T9 Mode” on page 56 for more information about using
the T9 Word text input mode.
