They are much more useful than it seems.
If you are used to working on a computer, you have certainly noticed that two keys – the F and the J, have small strokes. Chances are you’ve never really thought about this, but if you’ve ever wondered why these two keys are the only ones with this feature on the keyboard, know that there is a reason.
These markings, as discreet as they are, play a crucial role for keyboard users. They were designed to help with blind writing, that is, without looking at the keyboard. This is because the traditional ten-finger method of typing, taught since the days of typewriters, relies on what is known as the “basic position”. In this position, the index fingers are placed on the F and J keys, while the other fingers naturally rest on the adjacent keys. This layout allows access to all other keys with minimal movement.
Now imagine trying to find that basic position without looking at the keyboard, especially if you’re a beginner. Not easy, is it? That’s where those little strokes come in. They act as tactile guides, allowing your fingers to find their way without needing your eyes. In fact, they are to your keyboard what white lines are to the road, helping you stay on track.
This feature has therefore been present on keyboards since the days of the traditional typewriter. During the transition to modern computers, this detail has been retained on the keyboards that we all use. And these traits aren’t just useful for beginners. They are also valuable for experienced typists. When hitting intensively and quickly, it is easy to lose position. These guides provide a quick and easy way to refocus, without interrupting typing or wasting time visually searching for the right keys.
Finally, in addition to serving as a guide for those who use the keyboard without having to look at it while writing, these small lines are also useful for those who suffer from a vision problem and do not have a suitable keyboard at their disposal. .
