So why is there bumps on the F and J keyboard keys? Here’s the reason.

These are to help us position our fingers correctly so that we are able to type without looking at the keyboard. If you balance your hand correctly using these bumps it improves your typing speed and makes it easier to use the keyboard.

The F and J keys were specially used for this purpose. These keys are referred to as the home row. The bumps on these keys enable you to position your hands on the keyboard without looking in a manner that is optimal for touch typing. You are supposed to place the index fingers of your left and right hands over the ‘F’ and ‘J’ keys respectively. With your index fingers on the two ridged keys – your left hand covers A,S, D and F while the right covers J,K,L and colon. Both thumbs should rest on the space bar.
