If you've ever turned on the CAPS LOCK when you're sending an instant message or preparing a document -- but you don't intend to SHOUT -- you might want to set up a sound cue...
1. In Windows XP, click on the Start button
2. Click on Control Panel
3. Click Accessibility Options
4. In the Accessibility Options window, click the Accebility Options icon.
5. Then click the box next to Use ToggleKeys, and click the Apply button.
Now every time you hit the caps lock key, you'll hear a beep notifying you when the key has been pressed.
