These small features have a very specific origin and purpose. Keyboards, especially those used for extensive text input, are designed to maximize typing efficiency and speed. When it comes to typing without looking at the keyboard, correct finger positioning is crucial. However, the arrangement of letters on AZERTY keyboards – or QWERTY for English speakers – is neither natural nor ideal. It is inherited from ancient mechanical typewriters. In these devices, when two adjacent keys are pressed at or near the same time, their legs can collide or even get stuck. To solve this problem, manufacturers decided to move away from letters that are more likely to follow each other in words, even if it means making it more difficult to access certain keys. In addition, to make things easier for users, they had the ingenious idea of ​​adding tactile markings, in the form of bumps or grooves, on the most frequently used keys. If the stem problem no longer exists today in computers, the arrangement of letters on keyboards has not been as modified as usual, and manufacturers have kept the little typing trick of underlining the F and J keys.

The J and F keys were chosen as landmarks due to their central location on a standard QWERTY or AZERTY keyboard. These keys are the starting point for placing your fingers, which should naturally rest on the keys in the middle row, with your left index finger on the F key and your right index finger on the J key. As a result, the touch screen stroke lets you simply, even if you’re not Necessarily aware of this, quickly find the correct position of letters without looking at the keyboard. By feeling it under your fingers, you can quickly reposition your hands on the keyboard without having to look at them. Obviously, these little tactile cues are valuable if you use all your fingers in a typing position. But it’s also useful if you only type with two fingers!

So don’t forget that in order to type effectively with the AZERTY keyboard, you should position your fingers as follows:

  • Left index finger on F
  • Left middle finger on d
  • Left ring finger on S
  • Left little finger on Q
  • Right index finger J
  • Right middle finger on K
  • Right ring finger on L
  • Right little finger on M

Next time you put your fingers on the keyboard, remember that this little stroke is designed to make your typing smoother and more efficient. An important small detail!
