Windows stows away a setting that enables a beep whenever one of the lock keys are hit (Caps Lock, Scoll Lock, and Num Lock). For those of you who need extra notification when you accidentally hit the Capslock button, we’ll show you the quick Control Panel setting.
Open Control Panel, enter Accessibility Options, and check the box that says Use ToggleKeys. Hit OK and you now have auditory notification when you hit a “toggle key.”
