Using OnScreen Keyboard

An onscreen keyboard is in-built in Windows XP. It can be useful if you are using a tablet PC or if your keyboard goes on the blink. To access the keyboard, go to Start > Run, type OK and press [Enter]. The keyboard opens up on your computer screen, featuring three typing modes that you can use to type data:
Clicking mode: you click the on-screen keys.
Scanning mode: you press a hot key, or use a switch-input device, to type highlighted characters.
Hovering mode: you use a mouse or joystick to point to a key, which is then typed.
