Why are the letters on the keyboard not in alphabetical order? And why on the keys “A” and “O” (in the English layout – “F” and “J”) there are small convex dashes-tubercles? If you also asked these questions, but could not find answers to them, we suggest looking for explanations for these phenomena together.
The modern keyboard is a descendant of the typewriter, invented in the 19th century. Due to the design features of the mechanical device, the keys located at the edges of the typewriter were subjected to additional stress. This forced manufacturers to bring to the periphery of the letter rows the characters that were least used when typing. In the future, the keyboard layout was changed several more times, aiming to make it more convenient for typing, which in turn should have increased the speed of typing.

To do this, using the method of statistical calculation, the most frequently used letters and their combinations were determined – they were transferred to the center of the typewriter. Around these “main” symbols, lesser used signs were placed. As a result, the layout has acquired a modern look. As you may have guessed, the creators of modern keyboards borrowed it from old typewriters.

So what are the bumps on the keyboard keys “A” and “O” for?
As for the bumps on the keys “A” and “O”, here the situation is even simpler. The essence of this mysterious phenomenon lies in the method of blind printing. The latter assumes that a person will type text without looking at the keyboard. This significantly increases the speed of printing and makes the typing process easier and more efficient. The main feature of the method is that certain keys are assigned to each of the fingers.
The index fingers of both hands are “responsible” for rows containing the letter “A” on one side and “O” on the other. Since these symbols are the most commonly used, they are taken as a kind of starting point. The typist, thanks to raised dashes on the respective keys, can thus locate the buttons by touch without interrupting the typing process. This is the meaning of the marks on the keys “A” and “O”.
