QuickType is a Palm extension to help improve text input on Palm OS devices. QuickType is not a built-in keyboard or graffiti replacement. QuickType is a supplement. It makes it easier to input the more common information quickly. For punctuation, numbers, and special characters, you will still need to use either graffiti or the built-in keyboard.
Make sure you read the user suggestions at the end of the Manual. There are some great contributions by people including different methods of attaching overlays, a modification for OPTI for left handed users, and even a suggested German keyboard layout.
