Wish you could touch-type on your Palm, or enter Graffiti™ more quickly? The onscreen keyboard is simply too little to be effective - there is no way to fit 26 letters and related buttons onto the small screen.
Take a close look at what you write. You'll find that there are certain letters used much more frequently than others - in English, over 80% of text is made up of 12 letters.
DotNote Hack takes these common letters and lays them over the Graffiti area. Quickly enter common letters with a single tap, and use standard Graffiti to enter anything else.
