Get an alert if you hit the CAPS lock

Have you ever hit the CAPS lock by mistake without realising and typed a whole paragraph in uppercase? Windows actually has a setting that will trigger a BEEP when the CAPS lock is hit. To do that, just do the following:

1. Goto Start > Control Panel > Accessibility Options
2. Under the section ToggleKeys, check the option Use ToggleKeys
3. Click on OK

That's it. Now when you enable the CAPS lock, a high pitch beep will sound out. Hit the CAPS lock again and a low pitch beep will sound to signal that the CAPS lock is off.
