This is the arrangement order of all computer keyboard letters or English typewriter keyboard letters.
Interested readers may wonder: Why do you want to arrange 26 letters in this random way? It is difficult to remember and master. It is said that the reason is this:
19 In the 1970s, Shoals Company was the largest professional typewriter manufacturer at that time. Because the mechanical technology was not perfect at that time, the keys rebounded slowly after being struck. Once the typist hits the keys too fast, the two keys are easily twisted together and have to be carefully separated by hand, which seriously affects the typing speed. To this end, the company often receives complaints from customers.
Designers and engineers have racked their brains to solve this problem. Later, a clever engineer suggested that the reason why the typewriter twisted the keys was that the keys rebounded slowly on the one hand and the typist was too fast on the other. Since you can't improve the rebound speed, why not try to slow down the typing speed?
This is undoubtedly a new idea. There are many ways to slow down the typist. The easiest way is to disrupt the arrangement of 26 letters and put the more commonly used letters under clumsy fingers. For example, the letters "O", "S" and "A" are frequently used, but they are hit by the clumsiest right hand ring finger, left hand ring finger and left hand little finger. Unusual letters such as "V", "J" and "U" are handled with the most flexible index finger.
Thus, this "QWERTY" combination keyboard was born and gradually took shape.
Later, due to the development of materials and technology, the speed of keys bouncing back is much faster than that of typists, but the alphabetical order of keyboards cannot be changed. Up to now, there have been many reasonable letter design schemes, but none of them can be popularized, which shows how powerful the customary forces of society are. 2. 1860, in a Milwaukee newspaper, Christopher? Shoals works here. As an editor, he needs a lot of reports about the war every day. However, typewriters had taken shape at that time. According to his own impression, Shores made a machine that could help him finish the task faster. Because the mother and son were arranged alphabetically, Shores didn't think it was as useful as expected. Later, I revised the quotation and found that the keyboard formats we are using now all start with: q, w, e, r, t ….
