How it works
The top row is the row just above the home row. It has ten letters: q, w, e, r, t, y, u, i, o and p.
Each finger reaches straight up to its own top row key, taps it, and comes straight home.
The first six letters spell qwerty, which is why this is called a qwerty keyboard.
After every reach, the finger goes back home, so it never has to hunt for its key.
