There are two common ways to use a keyboard: you can use your pointers to hit one key at a time and spell out words and punctuation. This has also been called the “Hunt and Peck” method. Alternatively, it’s possible to place your whole hands down on the keyboard with fingers resting lightly on the A, S, D, F and ;, J, K, L keys, and thumbs hovering over the space bar.
You then lift one finger at a time to type a string of keys and spell out words through a series of coordinated and automatized movements. What’s different in the “touch typing” approach is that it requires a certain amount of beginner knowledge so you type the right keys with the right fingers. It also involves some fairly intricate movements that need to be rehearsed until they feel comfortable and you can execute them at top speed.
Lastly, you do it without looking down at the keyboard!
