How to type OF faster
O is typed with the right ring finger and F with the left index finger. Pairs that alternate hands are the fastest to type, because one hand gets ready while the other presses. The 136 Million Keystrokes study found that pairs typed by different hands or fingers are the strongest predictor of typing speed.
