Home Row Keys Explained: ASDF and JKL;
The home row is A, S, D, F under the left hand and J, K, L and the semicolon under the right. It is the position your fingers return to after every keystroke, and it is what makes typing without looking possible at all.
Where your fingers go
Left hand: little finger on A, ring finger on S, middle finger on D, index finger on F. Right hand: index finger on J, middle finger on K, ring finger on L, little finger on the semicolon. Both thumbs rest on the space bar.
Run your fingertips across the middle row of letters and you will feel a small ridge or dot on F and on J. They are there so you can find this position by touch, without looking — put your index fingers on the bumps and the other six fingers land correctly on their own.
Why everything starts here
Touch typing works because every key has a known position relative to a fixed starting point. Remove the fixed point and there is nothing to know a position relative to, which is why hunting and pecking never becomes automatic no matter how many hours go into it.
So the rule that matters is not where the fingers start but where they return. A finger reaches out to its key and comes straight back. Held out of position, the hand loses its reference and the next key becomes a guess.
What you can type with eight keys
More than it sounds. The home row alone gives you words like "flask", "salad", "lads", "fall", "ask" and "dad" — enough to practise real words rather than random letters from the first session, which matters because the rhythm of typing a word is part of what you are learning.
Adding just G and H, which the index fingers reach sideways for without leaving the row, opens up a great deal more. Most typing courses spend their first few lessons here for that reason.
How long to stay on it
Until you can find the position without looking and type simple home row words without hunting — usually a few days of short sessions, occasionally a couple of weeks. It is worth being slightly impatient here and then not moving on until it is genuinely automatic.
The mistake to avoid is treating the home row as a hurdle to clear before the real typing starts. It is the foundation the rest sits on: every key you learn later is described by its distance from these eight.
Try it
Take a one-minute typing test to see where you are, or drill the keys costing you the most time.
