Whats that gray area under PDA screens?

thanksssss!
is it there permantly? can you press a button and it dissapears so you have a larger screen?

Grafitti (sp?) pad. For handwriting recognition. You can write letters there and your PDA will recognize them.

The other icons are shortcuts to other functions of the PDA.
