Writing Pad /
Keypad
Use the writing pad to enter handwritten Graffiti characters.
Use the left side of the pad to enter alphabetic characters and
the right for numeric characters. Graffiti characters are similar
to normal characters but require fewer strokes (see Appendix
B).
You can also enter data using a pop-up keypad. Tap the “abc”
or “123” buttons to activate a pop-up keypad. Keypads make
it very easy to enter special characters.
