Home Row: Left Hand (A S D F)
a s d f
This is the first lesson in the practice path, and it starts with only four keys: A, S, D, and F. Rest your left-hand fingers on them now — pinky on A, ring finger on S, middle finger on D, index finger on F — and leave them there for the whole lesson. Every touch-typing method in wide use today starts from this exact hand position because it puts each finger at the center of its own natural reach zone.
If you've never deliberately trained a specific hand position before, this lesson will feel almost too simple — that's intentional. The entire practice path is built on the assumption that this exact starting position becomes so familiar it requires no conscious thought at all, and the only way to get there is to spend real, unhurried time on it before adding anything else.
What This Lesson Trains
The F key has a small raised bump on it (feel for it now) so your index finger can always find home position again without looking down — that bump is the single most important physical reference point on the entire keyboard for a touch typist, and getting used to relying on it starts here. Each of the four fingers should press straight down and immediately return to its home key; the temptation at this stage is to let the hand drift or to peek at the keyboard, both of which this lesson is specifically designed to break before they become habits. Because there are only four keys and one hand involved, this is also the easiest lesson in the entire path to do slowly and correctly — the goal here is not speed, it's building an accurate, unthinking placement you won't have to relearn later.
Pay attention specifically to your pinky on A: it's the weakest and least independently controlled finger you have, and if it feels awkward or uncertain compared to the other three, that's a completely normal reflection of real anatomy, not a sign you're doing anything wrong. Spending a little extra deliberate time on the A key specifically, rather than assuming all four fingers need equal practice, tends to pay off later once faster typing puts more demand on exactly this finger.

Frequently Asked Questions
Why only four keys in the very first lesson?
Starting narrow lets you build correct finger-to-key mapping without the distraction of a second hand or extra keys competing for attention. Every additional key in later lessons builds directly on the placement habits formed here.
What if my fingers keep drifting off A S D F?
That's normal at this stage. Glance down, reset to the home position using the F key's bump as your anchor, and keep going — the drift happens less each session as the position becomes familiar to your hand.
How long should I spend on this single lesson before moving on?
There's no fixed time, but a good sign of readiness is being able to return cleanly to A S D F after a short break in concentration without consciously thinking about where each finger goes — rushing past that point tends to cost more time later than it saves now.
Does it matter which order I press A, S, D, and F in during practice?
Not strictly, but deliberately varying the order (rather than always drilling left to right) forces each finger to move independently rather than relying on a memorized sequence, which builds more genuine, flexible key recognition than a fixed repeating pattern would.
