TYPING MISTAKES

Why you make the same typos every day

Keep a note of your typos for a week and the same few words will account for most of them. Errors in fluent typing are not random noise, they are a small number of specific mechanical faults, and each one has a different fix.

Typing errors are not random

If you keep a note of your own typos for a week, the same handful of words and letter pairs will account for most of them. So the fix can be targeted, which matters because general practice barely touches a transposition you make on one specific word.

Errors fall into a small number of kinds, and each kind has its own cause and its own remedy. Knowing which one you are making is most of the work.

Transposition: teh, adn, recieve

Two letters in the wrong order, and the most common error in fluent typing. It happens because at speed you do not send keystrokes one at a time. You dispatch a short sequence as a single motion, and the two fingers involved fire close enough together that the order can invert.

The tell is that transposition gets more common as you get faster, and that it clusters on words you type most often. Nobody transposes letters in a word they are typing carefully for the first time.

The fix is unintuitive: slow down on the words you know best. Type the at about 80 percent effort, deliberately, a few dozen times. You are not learning where the keys are, you are re-recording the timing of a motion you already have.

Substitution: the neighbouring key

Hitting the key next to the one you wanted. Almost always a sign that your hand has drifted off its home position, so the whole map is offset by one key.

If your substitutions are mostly horizontal, that is drift, and the remedy is returning your fingers to A S D F and J K L ; between words rather than leaving them where they landed. If they are mostly vertical, you are reaching without moving your hand.

Same-finger pairs, and why some words feel awkward

Some letter pairs make one finger do two jobs in a row. In QWERTY the reliably awkward ones are:

These are not your fault and no amount of general practice removes them, because the constraint is anatomical. What practice does is make the double movement smooth instead of hesitant. It is also the strongest single argument for alternative layouts, which mostly exist to break pairs like these apart.

The words that catch nearly everybody

Some words are hard because of how they are spelled, and the time they cost goes on hesitating over them more than on missing.

• Double letters in the wrong place. necessary, accommodate, occurrence, embarrass. The hand knows there is a doubled letter and guesses which.
• ie against ei. receive, believe, weird, achieve. Fluent typists often produce both spellings of the same word on different days.
• Words that end in a rolled sequence. rhythm, strength, twelfth. Three or four consonants with no vowel to break the motion.
• Your own name and email address. Typed so often they have become one gesture, so when they go wrong they go wrong the same way every time.

The two habits that cause errors indirectly

Typing at the edge of control. There is a speed above which your error rate climbs steeply. Practising above it teaches your hands that missing is part of the motion, and the threshold stays where it was. Most of a practice session should sit just below that line, where you can feel yourself being accurate.

Not looking at the screen. Typing while reading from paper, or with your eyes closed, removes the error signal entirely. You still get the physical repetition, but you stop noticing which repetitions were wrong, and that is the half that produces improvement.

How to find your own

Guessing is unreliable, because the errors you remember are the embarrassing ones rather than the frequent ones. Two ways to get real data:

• Keep a list for a week. Every time you press Backspace on a real document, note the word. Tedious, and it produces a list drawn from the text you actually write, which is the list that matters.
• Use something that records per key. Most typing tests report one accuracy percentage for a whole run, which tells you nothing about where the errors are. Per key measurement tells you it was Y and the semicolon, which is actionable.

What to do once you know

Build a short practice list from your own worst items, five to ten of them, and type only those for a while. Ten minutes on your actual problem words beats an hour of general practice, because ordinary English is roughly half E T A O I N S R H and your weak keys hardly appear in it.

Then stop, and go back to normal typing for a few days before you check again. The skill settles in between sessions, which is why a second hour on the same day is worth so much less than the first hour on the next.
