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