Old Skills records contain mistake counts, not how many times each key was attempted. They can suggest where to start, but cannot prove that a key has a higher error rate.

YOUR FOCUS

Practice deliberately

Select your commonly missed keys, begin with short drills and aim for high accuracy before speed.

01 / IdentifyFind error patterns from earlier typing exercises.

02 / ReinforceRepeat the difficult letters in words and pairs.

03 / CompareTrack your error rate across completed drills.

How weak-key analysis works

The keyboard map uses saved mistake counts. A fair error rate requires both the number of mistakes and the number of attempts for each character.

New Weak Key sessions measure both. Pressing Backspace does not erase previously made mistakes from your accuracy score.

Manual focus characters work even without past records.

How to improve a weak typing key

Choose a small focus

Practice three to five difficult characters at a time. Learn to hit each key accurately before increasing speed.

Mix isolated keys with real words

Single characters help with finger movement; words and sentences help transfer that skill to everyday typing.

Review your error rate

Compare several sessions rather than judging one attempt. At 98% accuracy, roughly two or fewer out of every hundred attempts are wrong.

Why are my recommended keys not always the slowest?

Older exercises stored the number of mistakes, not the number of attempts per key. Frequently used letters may have more mistakes simply because they appear more often. This page starts with their counts and measures rates in its own new sessions.

Can I practice Vietnamese or other languages?

Yes. Choose a supported word list. Composed Unicode characters are processed as grapheme clusters to support input method editors. The on-screen QWERTY map is only a visual aid for Latin keys.
