I found this in a few different places around the 'net - hopefully it's helpful:
Use the On-Screen Keyboard
An on-screen keyboard is built into Windows XP. It can be useful if you have mobility impairments, if you are using a tablet PC, or if your keyboard breaks down unexpectedly.
To access the on-screen keyboard:
- Go to Start, then click Run, and then type osk.
Now the keyboard opens on your computer screen, featuring three typing modes you can use to type data:
- Clicking mode, where you click the on-screen keys.
- Scanning mode, where you press a hot key or use a switch-input device to type highlighted characters.
- Hovering mode, where you use a mouse or joystick to point to a key, which is then typed.
To make a shortcut icon on your desktop to the on-screen keyboard:
- Right-click the desktop and choose New, then Shortcut.
- Type osk, click Next.
- Type a name for the shortcut, and then click Finish.
