Touchtyping is using all fingers on your hands and if any of you
do do that it's quite impressive, as you have to learn how to do it.
Personally, I only use the middle fingers of both hands (like Deffeh) and occasionally my index finger for things like backspace or enter. I don't have to look at the keys - that isn't touchtyping though. It's just not looking at the keys :P
My school's recently given/lent me a laptop and the / and \ keys are next to each other on the far right of the keyboard. It really messes me up
