What is the primary function of the home row keys in touch typing?

The home row keys serve as the starting position for fingers when touch typing, which is foundational for efficient and accurate typing. The home row includes the keys A, S, D, F, J, K, L, and the semicolon, and is where the fingers rest when not in use. By positioning the fingers on these keys, typists can quickly reach other keys without looking down at the keyboard, leading to improved speed and accuracy. This foundational positioning allows for the swift transfer of fingers to the other rows (top and bottom) while also aiding muscle memory, which is essential in developing proficiency in typing. Therefore, understanding the home row's role is crucial for anyone learning touch typing techniques.
