Here’s why the F and J keys on keyboards have bumps on them
When typing on a keyboard, whether on a laptop or PC, you will come across small peculiarities – for example, the bumps on certain keys. But what purpose do these small bumps actually fulfil?
These elevations serve a very practical purpose: they help you to find the keys and type blind. This technique, also known as blind typing or ten-finger typing, allows you to type faster and more accurately without having to look at the keyboard. It is based on feeling and muscle memory, which allows you to intuitively know the position of each key.
The placement of the bumps on the F and J keys on standard QWERTY and QWERTY keyboards is no coincidence. It serves as an orientation aid for the index fingers of the right and left hand. This makes it possible to find your way around any keyboard without affecting your typing speed. Keyboards with a numeric keypad often also have a raised section on the key with the number 5 to make it easier to navigate the number field.
