Why are there small lines on the F and J buttons of the keyboard? 99% people may not know the correct answer..

If you use a computer or laptop, then you might have seen these small raised lines on the keyboard. These marks are on the 'F' and 'J' buttons. You might not have paid attention to them, or even if you have paid attention, you might not know about their function. Many people do not know about this. Let us know what is the function of these marks.

Why are these marks made?

These marks are called Tactile Guides. Their job is to help you keep your fingers in the right place while typing, that too without looking at the keyboard. There is a special technique of typing - touch typing, in which you type through the muscle memory of the fingers, and not by looking at the keyboard again and again.

Why were 'F' and 'J' chosen?

In the standard QWERTY keyboard layout, the index finger of the left hand is placed on 'F' and the index finger of the right hand is placed on 'J'. The rest of the fingers are set on the buttons of their respective home row-

Left hand: A-S-D-F

Right hand: J-K-L-;

With the help of these small protrusions, the typist can quickly find the correct position without looking.

What are its benefits?

No need to look at the keyboard - You can directly focus on the screen and typing becomes faster.

Muscle memory is strengthened - By constantly placing fingers in the right place, your brain and hands get used to it, which reduces mistakes.
Posture and ergonomics are improved - Correct hand position reduces pressure on fingers and wrists, which reduces the risk of injury or stress injury.

Present on every keyboard.

These marks are found on almost every physical keyboard, be it desktop or laptop. Some touchscreen keyboards and Braille devices also have similar tactile features, so that users can type easily without looking.
