Its happened to all of us at one time or another. The Caps lock is turned on accidently and you are typing away only to eventually notice that you are typing all CAPS. You then have to re-type it all. Well, there is a little method of flashing the active window whenever you tap the CAPS lock. To do so, go to your Control Panel and Accessibility Options. On the keyboard tab, check on the ToggleKeys option. Then go to the Sound tab and enabled SoundSentry. Choose “Flash Active Window” as your visualization method. Apply your changes and hit OK. Then, go to a text editor and hit your CAPS lock. You will hear your PC make a little beep from the PC speaker as well as the window will flash.
