It is not noticeable at first but there are two keys on your keyboard that have small notches on them, let’s find out why.
While many of us may not have noticed the bumps on ‘F’ and ‘J’ on every standard keyboard, professional typists have good use of these.
To find out the reason, you will have to place the two index fingers and as soon as you do so, you will realise that it is the optimal placement of hands on the keyboard.
Practically, professional typists have no time to look down on the keyboard while typing. While directly looking at their copy, the typists type at very high speeds making use of the bumps.
This is done by placing the left index finger on the ‘F’ key and the right on the ‘J’ key, allowing access to all keys with as minimum movement as possible.
Simply stated, the bumps are there to be able to identify the keys without having to look down on the keyboard time and again.

Placing the fingers on the bumps are called ‘home row’, meaning the row where typists rest their fingers, with the notches available virtually on all keyboard including the QWERTY and Dvorak ones.
