How to practise your weak keys and letter pairs

Weak keys vs. weak letter pairs

A weak key is one you often press wrong, like hitting 'n' when you meant 'b'. A weak letter pair is a move between two keys, like t → h or e → d, that you get wrong or do slowly even though each key on its own is fine.

Pairs matter because typing is a chain of movements. Same-finger jumps (where one finger types both keys) and neighbouring weak fingers, like the pinky and ring finger, are the usual problems.

How FastFingers finds them

Every time you type on FastFingers, it records each key and each letter pair: whether you got it right and how long the move took. Sign in and your progress page lists your most-missed keys, your error-prone pairs and your 'hesitation pairs', the ones you type correctly but slowly.

Each one has a one-click drill that takes you to the AI Coach with practice built around exactly those keys.

Tips for drilling

Go slower than feels natural and press each key on purpose. Keep your fingers on the home row and return there after every reach.

Practise in short sessions, a few minutes at a time, and come back the next day. Then take a normal test to check the improvement carries over.
