Hello! I am addressing people in the IT field and acquaintances. I'm very curious what these slightly protruding lines on the F, J & number 5 buttons on the right of the keyboard are. I have always wondered a lot, but I did not find the necessary information anywhere. What is this thing for Thanks in advance.

This is a marking that makes it easier to position your fingers on the keyboard. The starting position when writing on the keyboard requires the pointers of the left and right hands to be set to F and J., respectively. This can be done automatically without looking at the keyboard precisely because of the protrusions.
I wasn't sure, but I think that will answer your question. Braille keyboard This is a hardware input device that is designed as a convenience for blind computer users. Pressing a certain key on the braille keyboard displays the data displayed on the key, just like with a standard computer keyboard or typewriter. The difference is that there are protruding dots on the keys of the Braille keyboards, which correspond to the given letter in the Braille letter. Some keyboards have keys that replace the mouse, as well as keys that replace basic keyboard shortcuts. An ordinary keyboard can be adapted as a Braille one by sticking special stickers with Braille dots on the ordinary keys. Blind users generally use a regular keyboard without any extras, as there are protrusions on some of the keys, which serve as a guide when typing. For this purpose it is necessary to master the ten-finger writing system.
Makes writing easier. You can always pick up the small bumps and from there find out where the other buttons are, without having to look at the keyboard. And looking at the keyboard is bad, because slowing down your typing leads to mistakes.
A landmark for the blind, I guess?
Letter marks are markers that help you write quickly on ten-finger or other systems. The left index finger is placed on F and the right index finger on J. And the marker of the five in the digital block is for blind people. It is everywhere - on old phones, on calculators, even on remotes.
These small protruding rulers are just a guide to where these letters F and J and the number 5 are. This landmark is used for typing on the keyboard without looking at it, and especially with the ten-finger typing system without looking at the keyboard. The letters F and J must be marked on the left and right hands, respectively. In addition to these two letters, the pointers can serve all other letters vertically on this letter. For example: The left hand pointer serves the vertical of F (4, R, F and V) as well as the vertical of G (5, T, G, B) in the ten-finger keyboard typing system. The index finger of the right hand will serve the vertical of J (7, U, J, M), as well as the vertical of H (6, Y, H, N). The other fingers 3, 4 and 5 fingers are located on the buttons to the side of the index keys and each of them serves its own vertical buttons. The thumbs serve the long Space key (the space key). On the right in the numeric section "Number Lock", the 3rd finger must be placed on the key with the number 5. This 3rd finger also serves the entire vertical of the keys of the number 5. (/, 8, 5, 2) And the 2nd and 4th fingers serve the left and right verticals of the numeric keys, which are to the left and right of the number 5) In short, when we type on the computer, we should not look at the keyboard, but internally mentally imagine the location of the keys.
