Topic: keyboard lights and sounds

[joudi]

Sure your keyboard has small lights (LEDs) to indicate if your CAPS, NUM and SCROLL lock keys are on or off. When you're busy typing you might accidentally hit one of these locks which might force you to retype.
 
Here's how to make your computer beep whenever any of the lock keys change state:
 
Go to the Control Panel
 
Double click Accessibility Options
 
Turn on the ToggleKeys checkbox
 
Click OK
