The F and J keys on most QWERTY keyboards have small raised bumps to help users locate them by touch. These bumps serve as tactile guides for touch typists, allowing them to position their fingers correctly without looking at the keyboard. This design detail improves typing efficiency and accuracy by providing physical reference points for the left and right index fingers.
