Traditional text input
Tap a number key (1-9) repeatedly until the desired character appears. There are
more characters available for a number key than are visible on the key.
If the next letter is located on the same key as the present one, wait until the cursor
appears (or move the cursor forward to end the time-out period), and enter the
letter.
To insert a space, tap 0. To move the cursor to the next line, tap 0 three times.
