F is the 16th commonest letter in English prose: 1,143,906 of the 51,993,314 letters in the 111 public-domain books this site cuts its practice texts from — 2.20%, or once every 45. On a QWERTY keyboard it is a home key, so the left index finger is already on it and there is no reach to get wrong. The pairs it turns up in most are FO (189,124), FE (97,966), FR (88,316) going out of it and OF (367,600), IF (81,512), EF (58,304) coming into it, so those are the two-key rolls worth getting smooth. In the course it arrives in lesson 1, the F and J keys.

The pairs it lives in

Two-key rolls are what fast typing is made of: practise the pair, not the letter.
