Which finger types which key
Each finger owns a column and returns to one home-row key between presses. Left hand: little finger on A, ring on S, middle on D, index on F and G. Right hand: index on J and H, middle on K, ring on L, little on the semicolon. The two index fingers cover two columns each, which is why they do roughly twice the work of any other finger.
The assignment, finger by finger
Eight fingers, four rows, and a little over forty keys. The assignment below is the one every touch-typing course teaches and every keyboard is built around, and the whole of it follows from one idea: a finger rests on a home key, leaves it to press something in its own column, and comes straight back.
Read the table by finger rather than by key. What you are memorising is not forty separate facts but eight small territories.
| Finger | Home key | Also reaches |
|---|---|---|
| Left little | A | Q, Z, 1, the backtick, Tab, Caps Lock, left Shift, left Ctrl |
| Left ring | S | W, X, 2 |
| Left middle | D | E, C, 3 |
| Left index | F | R, T, G, V, B, 4, 5 |
| Right index | J | U, Y, H, N, M, 6, 7 |
| Right middle | K | I, the comma, 8 |
| Right ring | L | O, the full stop, 9 |
| Right little | Semicolon | P, the slash, 0, hyphen, equals, both brackets, the backslash, the apostrophe, Enter, Backspace, right Shift |
| Thumbs | — | The space bar, with one thumb rather than both |
Why the index fingers get two columns each
There are ten columns of letters across the middle of a QWERTY board and eight fingers to cover them, so two columns have no finger of their own: the T-G-B column and the Y-H-N column, sitting either side of the middle. They were given to the index fingers, and the reason is anatomy rather than tradition.
The index finger is the most independent digit on the hand. It can move without dragging its neighbours along, which the ring finger in particular cannot — try lifting a ring finger while the middle and little fingers stay down and you will feel the tendon that connects them. It is also the strongest of the four and has the longest comfortable sideways reach. Giving it the extra work was the least bad option available.
The practical consequence is worth knowing before you blame yourself for it: the index fingers are doing about twice the keystrokes of the others, and if any finger is going to feel slow or clumsy while you are learning, it will be one of those two. That is the design, not a fault in your hands.
The keys people actually get wrong
Most of the assignment is uncontroversial and most people arrive at it on their own. These five are where self-taught typists and courses diverge, and where a habit is usually worth correcting.
- B
- Officially the left index, reaching down and right from F. It is by some distance the longest reach in the standard assignment, and a great many otherwise orthodox typists use the right index instead. This is the one key where the alternative is genuinely defensible — pick one and be consistent.
- Y
- Right index, reaching up and left from J. Frequently typed with the left hand by people who learned by imitation, which puts two consecutive left-hand motions into words like "type" and "you" and costs more than it looks like it should.
- The number row
- Almost everyone abandons the assignment here and looks down. It is the least practised part of the board by a wide margin, and it is the part where looking down costs the most, because the eyes have to travel furthest and the hands have to re-find the home row afterwards.
- Hyphen and equals
- Right little finger, and the longest reach on the board. If you are moving the whole hand to get to them, the anchor is gone and the next few characters will be slower than they should be.
- Backspace
- Right little finger. Worth naming because it is pressed constantly and almost nobody thinks of it as a typed key. A typist who lifts the whole right hand to correct a mistake pays for the correction twice.
Thumbs, Shift, and the keys no course assigns
The space bar goes to one thumb. Which one does not matter, and the usual advice to use the thumb of your dominant hand is as good as any. What is worth avoiding is choosing unconsciously each time: the point of a fixed assignment is that the motion stops needing a decision, and a space that might come from either thumb is a decision made several times a second. Some very fast typists do alternate deliberately, taking the space with the hand that did not type the last letter — that is a rule too, and it is the having of one that matters.
Shift is the rule most often broken and the easiest to fix. The Shift key is always pressed by the hand opposite the letter: left Shift for a right-hand letter, right Shift for a left-hand letter. Using the same hand for both forces one hand into a contortion and takes it off the home row, which is why capital A is slow for so many people who are otherwise fluent — they are reaching for left Shift with the little finger that also has to press A.
Ctrl, Alt and the modifiers below the board are the one place where no standard assignment survives contact with real use, because what they do depends entirely on what you are using. Programmers and anyone who lives in keyboard shortcuts end up with their own arrangement, often remapping Caps Lock — the most valuable real estate on the board, given to a key almost nobody wants — to something they press constantly.
Does the assignment actually matter?
Less than the way it is usually taught implies, and more than sceptics claim. It is worth being precise about which.
What matters is that every key has exactly one motion, starting from one resting position. That is what allows the motion to become automatic, and automatic motion is the whole of typing speed. A self-taught typist with a non-standard but genuinely consistent assignment can be very fast, and some are.
What does not work is an assignment that changes depending on what you typed last — B with the left hand sometimes and the right hand other times, a space from whichever thumb is nearer, a hand that drifts and re-anchors somewhere new. Every one of those keeps a decision in the loop, and a decision is roughly a tenth of a second that repetition never removes, because there is no single motion being repeated.
So the standard assignment is worth learning not because it is optimal — it is a reasonable compromise reached a long time ago — but because it is a complete, consistent answer that somebody else has already worked out, and because it is what every course, every keyboard bump and every piece of advice you will read assumes.
Questions
Which finger types B?
The left index, in the standard assignment: down and right from F. It is the longest reach on the board and a large minority of fluent typists use the right index instead. Unlike most deviations this one is defensible, because B is nearly equidistant. What matters is that you always use the same one.
Should I use both thumbs for the space bar?
Pick a rule and keep it. One thumb, usually the dominant one, is what every course teaches and it is the simplest rule to hold. Deliberately alternating — the hand that did not type the last letter — is also a rule, and some very fast typists use it. What does not work is deciding afresh each time, because then nothing becomes automatic.
Which finger presses Shift?
The little finger of the hand opposite the letter — left Shift for a right-hand letter, right Shift for a left-hand letter. Using the same hand for both pulls that hand off the home row and is why capital letters on the left of the board are slow for many otherwise fluent typists.
Do I have to use the standard assignment?
Not strictly. What you cannot do without is consistency: one motion per key, from one resting position, every time. The standard assignment is worth learning because it is a complete and consistent answer somebody has already worked out, and because it is what the F and J bumps, every course and every keyboard are built around.
What about the number row — do I need to touch type it?
If you type numbers in any quantity, yes, and it is the least practised row on the board precisely because most people decided the answer was no. Looking down costs more there than anywhere else: the eyes travel further and the hands have to re-find the home row afterwards.
Put it into practice
Reading about typing is the smaller half. The beginner course starts on the home row, the speed test will tell you where you stand, and all of it works in 86 languages without an account.
