Why aren't the letters on the keyboard arranged in ABC ... Thank you, everyone.

The letters on the computer keyboard are out of order. Maybe you will wonder: Why are the letters arranged in the same order on all computers, printers and typesetting equipment? Why is the distribution of letters not arranged in alphabetical order, and there is no rule to follow? The answer is this: When Sauers built a typewriter, he was surprised to find that a typist always broke down during normal typing. To solve this problem, Sauers went to his brother-in-law, a mathematician and school teacher, for help. His brother-in-law put forward a solution: separate the commonly used connected letters on the keyboard, so that the speed of keystroke will be slightly slower and the occurrence of faults will be reduced. Shores happily adopted his brother-in-law's suggestion and arranged the letters in a strange QWERTY keyboard order. Sauers told the public that in order to avoid failure, the letters must be arranged out of order, which may be embarrassing. So he cleverly played a trick, saying that this arrangement is the most scientific and can speed up people's typing. In fact, Sauers' statement has been recognized as "one of the biggest cheating activities in history" and "a complete lie" by the authorities in the history of British typewriter development. Strangely, those more scientific keyboards designed by Sauers have been eliminated by history, but people are beginning to get used to using this strange arrangement of keyboards. People have spent centuries trying to invent typewriters. In England, Henry Mill applied for a patent for a machine. The name of this machine is "man-made machine or tool for copying letters" With it, you can write a single letter or several letters in succession, just like writing. All written contents can be neatly and accurately copied on paper or parchment in capital letters, which is comparable to printing. That machine may not be sold because no one remembers its name. The first typewriter used was Christopher latham's 1868. Shoals obtained the patent right. His machine is called a typewriter. He has a movable shelf, a joystick for changing typing paper and an alphabet keyboard. But there's a problem with the shallows. In his original model, this arrangement of "ABC" keys often caused a key card when the typist typed quickly. Shoals doesn't know how to keep these keys from interfering with each other. His solution is to ask typists not to type too fast. Shoals asked his brother-in-law to rearrange the keyboard, so that the most commonly used letters would not be tested too close, and the type linkage could move in the opposite direction, so as not to collide and block the machine. The new arrangement is the QWERTY arrangement used by typists today. Of course, Shoals said that the new arrangement is scientific and can improve speed and efficiency. In fact, the only efficiency it improves is to slow down the typist, because almost no matter what word is typed in English, the typist's fingers are required to span a longer distance on the keyboard. The advantages of typewriter certainly outweigh the disadvantages of this keyboard. Typists soon remembered this strange arrangement of letters, and the typewriter was a great success. By the time the typist remembers the new arrangement of letters, the typing speed has improved, the production technology of typewriters has also improved, and the letter keys are no longer blocked as easily as they were at first. At present, the keyboard invented by Shoal is really not so good, and the arrangement of letters has too many shortcomings. For example, eight of the most commonly used letters 10 in English are too far away from the designated finger position, which is not conducive to improving typing speed; In addition, there are too many letters on the keyboard that need to be typed with the left hand, because most people are right-handed, and there are only 3,000 words in English that can be typed with the left hand, which is awkward to use. Some people have done statistics, using QWERTY keyboard, a skilled typist can move his fingers 25.7 kilometers in 8 hours, and he is exhausted at the end of the day. Unfortunately, thousands of people have become accustomed to it. Today, QWERTY keyboard still firmly occupies the input field of computer. Although some people have designed more scientific arrangement keys, they still can't become a climate. Modern computer keyboards don't have any cumbersome metal bars, which is of course unexpected for shoals. Many people are confused about the alphabetical order of computer keyboards. B is not next to A, but P and Q, which should be connected, are on their own side, far away from each other. What is the reason? In fact, the original design concept of this keyboard is to let you play fast! At present, the keyboard commonly used by the public is called "fast hoof keyboard", and the original text is "QWERTY". Has anyone found that this word looks a little familiar and unfamiliar, but it is actually a combination of the first row of letters on the keyboard? Please look at the following three rows of letters: QWERTY Y U I O P A S D G H J K L Z X C V B N M The first typewriter came out in 1868, which 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. The original keyboards were basically arranged in alphabetical order, but in order to prevent the typewriter from hitting too fast, the mechanical rods supporting the keyboards collided with each other and caused failures, so the positions of some letters were adjusted, forming today's appearance. It is said that the reason is this: in the 1970s from 65438 to 2009, Sholes Co was the largest manufacturer specializing in the production of typewriters. Because the mechanical technology was not perfect at that time, the keys rebounded slowly after being hit. 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. In order to solve this problem, designers and engineers have been racking their brains, because there is really no way to improve the rebound speed of keys. Later, a clever engineer suggested that on the one hand, typewriters twist keys slowly, on the other hand, typists type keys too fast. Since we can't increase the speed at which the keys pop up, why not try to slow down the typist's keystrokes? This is undoubtedly a new idea. There are many ways to slow down the typist's keystrokes. The easiest way is to disrupt the arrangement of 26 letters and put the more commonly used letters under clumsy fingers. For example, the letter "O" is the third most commonly used letter in English, but it is placed under the ring finger of the right hand. The letters "S" and "A", also commonly used letters, are used for the clumsy left hand ring finger and little finger. In the same way, 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. This arrangement really brings a lot of trouble to beginners in input. In fact, as early as 1936, some people noticed this problem and introduced a more ergonomic keyboard. Unfortunately, this keyboard died in World War II before it went on sale. Recently, a group actively promoted this keyboard named "Devzak", and perhaps in the near future, the new letter arrangement will be widely adopted.
