What letters are the letters after the A and V on the keyboard

This actually refers not to the back, but to the right, and next to A is S, and V is next to B.

Extension: The keyboard letters are sorted according to the frequency of the letters. It's hard to memorize and hard to master. The reason for this is said to be this:

In the 70s of the 19th century, Shores was the largest manufacturer of typewriters at that time. Due to the imperfection of the mechanical process at that time, the rebound speed of the word key after hitting is slow, once the typist hits the key too fast, it is easy to occur the phenomenon that the two word keys are twisted together, and they must be separated very carefully by hand, which seriously affects the typing speed. For this reason, the company often receives complaints from customers.

To solve this problem, designers and engineers struggled with their brains. Later, a clever engineer suggested that the reason for the typewriter twisting the keys was, on the one hand, the slow return speed of the word keys, and on the other hand, the speed of the typist.

Since we can't increase the bounceback speed, why not think of a way to slow down the typing speed.

This is undoubtedly a new way of thinking. There are many ways to slow down a typist, but the easiest way is to shuffle the order of the 26 letters, placing the more commonly used letters, such as letters, under awkward fingers"o"、"s"、"a"It is used very frequently, but it is struck with the most clumsy right ring finger, left ring finger and left little finger. Less frequent use"v"、"j"、"u"and other letters, but the most flexible index finger is responsible.

As a result, this kind"qwerty"The keyboard was born and gradually finalized. Later, due to the development of material technology, the speed of the word key bounce back was much greater than the speed of the typist's keystroke, but the keyboard alphabetical order could not be changed. So far, there have been many more rational alphabetical design schemes, but none of them can be generalized, which shows how powerful the customary forces of society are.

1. ESC key: exit key.

2. Shift key: Commonly known as the up key. Press and hold the key, then type a letter.

The letter came out in capital letters. It can also be used for Chinese-English conversion. Wait a minute.

Press and hold this key, then press the number key, and the symbol above the number key will be displayed.

3. Ctrl key: commonly known as control key, generally used in combination with other keys. For example, the most commonly used key is: ctel+c=copy ctel+v=paste c.

4. Capslock key: letter case conversion key. Every time you press 1 conversion, there is a corresponding case indicator in the upper right corner of the keyboard that will turn on and off (the green light is uppercase input mode, otherwise it is lowercase input mode).

5. Shift key: commonly known as the up-to-back conversion key. Hold down this key, and then type the mother, and what comes out is the uppercase of this letter. It can also be used for Chinese-English conversion. And so on, hold down this key, and then hit the number key, and the symbol above the number key will appear.

The computer keyboard is a channel that inputs the control information of text information into the computer, which evolved from the English typewriter keyboard. When it first appeared on computers, it was a component called a "teletypewriter".
