It is what i used in typing class (they wanted you to take that before computer class in the 80s). To this day I'm a touch typer ,and know instantly when i have mad a mistake.
Indeed, probably the most useful class I ever took was typing. It is interesting how you can actually "feel" a typing error when you touch type, without even looking at the screen/paper. In most cases I can actually correct without looking at the screen or the keyboard.
