How it works
Each button on a keyboard is a key. Press a key and the computer hears it: one press, one mark.
The letter keys sit in three rows: the top row, the home row in the middle and the bottom row. Number keys run above them, and the long space bar lies below.
Letter keys make a letter. Job keys, such as shift, enter and backspace, do a job and never make a letter by themselves.
Know the row, and your finger can walk straight to the key.
