Ridges on the F and J button buttons

The ridges are called the "Home Row". Those little bumps on letters “F” and “J” are for proper position of hands on typing, the “F” is for left index finger and the “J” is for right index finger it should be in the starting position when you are going to type if doing it properly and the keypad number 5 also has ridge. The people who use this are called touch-type (type without looking) use these two ridges to determine the position of their fingers on the keyboard. Touch typing people use the ridges on the "J" and "F" keys to type without looking. Amazing, right? It’s so great how people invented these small ridges with a great use on typing.
