Many of you will know this but, are you like me with clumsy fingers on the keyboard? You've been typing away for ages. You eventually look at the screen to find that half way through your life's story you've acCIDENTALLY HIT THE cAPS lOCK BUTTON.
XP has a little audible helper here. Click on Control Panel then Accessibility Options. On the Keyboard tab, tick Toggle Keys and from then on your computer will beep every time you hit the Caps Lock, Num Lock & Scroll Lock buttons.
Is there something out there which inverts letters?
So if you highlight something and hit something it inverts the letters (lowers to caps, caps to lowers)
