How to type TH faster
T is typed with the left index finger and H with the right 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.
