Home Row Keys: How to Find F and J Without Looking

datum key is the positioning reference

Common QWERTY fingering Put your left hand on A, S, D, F, and your right hand on J, K, L, near the semicolon, the thumb is responsible for the space. Tactile markings on F and J help you find the starting point without looking down. This set of instructions is specific to this layout; other layouts, ergonomic keyboards, or personal movement needs should be adjusted based on actual key positions and comfort ranges.

Don’t interpret “returning to the base position” to mean that you have to square your hands hard every time you press a key. It's more like a reference point on a map, letting your finger know where it is even after moving around. Continuing to press the keycaps stiffly will make the movement unnatural.

Separate positioning and speed

In the first round, just do the cycle of letting go, positioning, lightly pressing, and releasing, and observe whether it often deviates from one column. Only enter simple combinations in the second round, such as fj jf dk kd. Leave a little space between each set, and focus on whether the target finger is in the right position, rather than how many times you press it.

If a certain finger always moves together with its adjacent fingers, first narrow down the task and practice only two adjacent keys. There is no need to lift the other fingers very high or force them with your other hand. If you can't find the key, you can check the layout, come back and try again.

How to expand to more keys

After the reference row is stable, add a small amount of upper or lower row keys at a time. Practice new keys independently first and then put them back into short words. For example, after you are familiar with the movement from f to r, try entering simple words containing r. This way you can check that you're learning actual moves, rather than just memorizing a set rhythm.

Today’s practice

Enter as df jk l; for three rounds, then type sad, fall, ask and other short words. Finally, switch to a combination that you haven’t memorized before. If you can't find the key at all when you change the topic, continue to practice positioning next time; if you are just slow but can input correctly, you can gradually expand the range and don't have to wait until the speed is very high to learn new keys.
