home keys
home row keys

    The eight keys on a typewriter or computer keyboard
   on which a touch-typist positions their eight finger tips when
   starting to type or when resting between words or phrases.
   Typists learn the position of all keys on the keyboard in
   relation to the home keys.

   On a standard english keyboard layout, the home keys are ASDF
   for the left hand and JKL; for the right.  Most keyboards have
   small raised bumps on the left and right index finger keys (F
   and J) so you can find the home keys by touch without looking.
