Everybody in the world except me may already know this. I just found it and it is very helpful to me and hopefully to a few hundred or few thousand other users. This may have been available in Vista and possibly even XP, but I know it is available in Windows 7. If you frequently accidentally hit Caps Lock while typing, you may want to make your computer make a sound when the caps lock key is pressed. Go to "Control Panel"> "Ease of Access Center"> "Change How Your Keyboard Works"> "Make Keyboard Easier to Use"> "Make it Easier to Type". Check the check box for: "Turn on Toggle keys". After checking the required checkbox, exit back to your desktop. You will now hear a tone when you hit "Caps Lock", "Scroll Lock", or "Num Lock". (Make sure you keep your sound turned on) I use Master Task Mode (aka God Mode), so if you use the default Windows Control Panel, you may have to do a bit of searching to find the above path. It is well worth the seARCH TO PREVENT THIS MISTAKE. Good luck to all.
