Meet the F key

Which finger types this key

A browser can only report which character was typed, never which finger pressed it. That is why this lesson blocks on the wrong key rather than claiming to detect the wrong finger — the finger is something you have to build the habit for, and the table below is the habit to build.

f

Left index finger, home row — where the left index finger already rests.

How often you will actually type these

In ordinary written English, F accounts for about 2.23% of letters. Together that is roughly 2.2% of everything you type, so the time spent here is repaid across every word you write afterwards.

Where the mistakes come from

Errors are rarely random. A wrong key is usually the right finger travelling the wrong distance in its own column, which is why the fix is control rather than slowing down everywhere.

f

Most often mistyped as 4, 5, r, t, g, v, b — the other keys the left index finger is responsible for.
