Why do the F and J keys have a hairline on the keyboard?

Perhaps you find it curious that your keyboard contains a small relief in the letters F and J . You should know that this is not pure chance and that behind this there is a logical and quite important reason, especially for people who use typing .

Contrary to what many people may believe, these scratches on the F and J keys are not useless, as they have a very particular functionality. First of all, these reliefs indicate which is the middle of the keyboard and what allows you to position your fingers correctly to start typing.

This also indicates that on the letter F and J you must place your index fingers to be able to use the keyboard without looking at it. You may wonder why we should place our index fingers and not someone else? Well, it must be taken into account that these fingers have more movements and facilitate the writing process.

Remember that the better you follow these typing rules, the easier it is to write and you can even do so without looking down at the keyboard. If you want to know more about the correct way to write on the keyboard using the relief located in the letter F and J, keep reading this article and you will know everything you need to increase your writing skills.

What is the story behind the bulge under the letters F and J and what is it for?

In 2002, June E. Botich had the great idea for keyboards to contain a stripe on the letter F and J to serve as reference guides to enhance keyboards.

Location system

It is true that the hatches in the letters F and J on the keyboard have a rather specific function . This has a reason and it is that they are reference guides so that you can use the keyboard in a better way. If you use this location system correctly, you can improve the learning process and train typing.

Write without looking at the keyboard

That the keyboards have these scratches included can help you locate your hands on the keyboard in the correct letters without the need to look down to see where they are located. This means that using these lines as a reference, you can get as a result typing faster without having to look at the keyboard , but only look at the screen.

Location in the numbers with the ‘number 5’

There are some keyboards that contain a number pad on their right side. It also has its own orientation to make it easier and more practical to use. The relief that contains the letter F and J on your keyboard, also contains the number 5 .

Nowadays this is not used as much because of the change in the design of the keyboards, but if you have a slightly older keyboard, it is likely that you can find this hairline.

What is the correct way to type on the keyboard without seeing?

So you can type without looking at the keyboard requires practice , but the relief in the letter F and J serve as a guide for you to achieve it. The ideal would be to write with the ten fingers of your hand and for this it is recommended that you learn about typing.

Although it is true, you have to start by understanding that the index of the left hand should be located on the letter F and the index of the right hand on the letter J.

Why are there keyboards that don’t have a stripe under the letters F and J?

Modern keyboards have a small relief in the letters F and J . However, there are keyboards that do not have it and the reason is that they are very old models.

Old versions of the keyboard

If you have a very old keyboard, it is very likely that you will not get this relief on the F and J keys and this has a reason. Keep in mind that the idea came about in 2002, so if you have a keyboard manufactured before that year, it will not have the relief.
