Why are there bumps on the F and J keyboard keys?

Updated: 08/31/2020 by Computer Hope
Keyboard bumps

The small bumps or ridges found on the F and J keyboard keys (position keys) help position your left and right hands without having to look at the keyboard. For example, without looking at your hands, you can feel the small bumps to correctly position your left and right index fingers on the F and J keys. Once your hands are on the home row key position, you're able to locate the remainder of the keys on the keyboard.

Tip

The number 5 on keyboards with a numeric keypad also has a bump to help position your hand on the key pad.
