A silly question from a hunt-and-peck typist: am I the only idiot who madly types away, inadvertently hits the "CAPS LOCK" key, and finds he has to erase the last ALL CAPS sentence and re-do it? (The Big-A-Looping-Arrow-Little-A format button in MS Word doesn't help... I don't think!) Is there a simple piece of software which would DING! when I hit the Caps-Lock key? Grazie!
