If you work on a computer or laptop, take a look at your keyboard. You will see small raised lines or bumps on the 'F' and 'J' keys. Have you ever noticed why these are there?

Many people consider them just a part of the keyboard's design, but they have an important purpose. These small bumps are a special technical trick that helps in making typing easier and faster.

When a typist types without looking at the keyboard, he has to guess the correct position of his fingers only by touch. That is why there are these markings on the 'F' and 'J' keys of the keyboard.

These two small lines are very useful.

These bumps tell the user where to place their index fingers (first fingers). When these fingers are in the right place, the rest of the fingers are automatically set to the correct position.

This is called the ‘home row position’, from where typing starts—A, S, D, F for the left hand and J, K, L, and ; (semi-colon) for the right hand.

No need to look down repeatedly

The advantage of this feature is that there is no need to look down repeatedly while typing, which increases typing speed and reduces the chances of mistakes.

So the next time you use the keyboard, do not ignore these small lines. This is not just a design, but a smart innovation which helps you start typing from the right place every time.
