Home row keys
Term used to describe the row of keys on the computer keyboard your fingers rest on when not typing. For example, on the standard QWERTY United States keyboard, the home row keys for your left hand are A, S, D, and F and your right hand are J, K, l, and ; with the thumbs resting on the space bar.
On the Dvorak United States keyboard, the home row keys on your left hand are A, O, E, and U and your right hand are H, T, N, and S with the thumbs resting on the space bar. The letters on the home row can increase or decrease the speed of your overall typing, which is one of the many reasons Dvorak keyboard users can type faster than QWERTY keyboard users.
