Re: "most of us are trained in touch-typing"
Agreed. I can type as fast, if not faster, than a trained touch typist (approx 90wpm, not world beating I know, but fast nonetheless)...but I don't use typical touch typing technique. My hands are all over the place...trying to work out my typing pattern would be hard, because I don't actually have one...especially if I'm at a desk with two keyboards where I generally type one handed.
