Which is the keyboard enter key?

question 1: which is the Enter key? I don't understand it at present. There are usually two enter keys on a 4-point universal keyboard. Generally, there is a key with the word "Enter" written on the middle right side of the keyboard and a curved arrow, which is called the "Enter key" (main enter key). In addition, there is an "Enter key" (auxiliary enter key) on the lower right edge of the keyboard, as indicated by the red arrow in the figure below.

main "Enter key" diagram:

About the origin of "Enter key", we have to start with the mechanical English typewriter. On the mechanical English typewriter, there is a component called the "word car". Every time a word is typed, the "word car" advances one space. When a line of characters is filled, the typist has to push the "carriage" to the starting position. At this time, the typist will respond with two actions: one is that the "carriage" is reset, and the other is that the roller rolls up a line to start typing the next line. This action of pushing the "carriage" is called "enter". Later, on the electric English typewriter, people added a key that directly played the role of "Enter". This new key is called "Enter".

on the computer keyboard, the words "CR" and "RETURN" were once used on the "Enter" key, and later they were uniformly defined as "Enter".

Enter key has two functions, one is to confirm the input execution command, and the other is to play the role of line breaking in word processing.

Enter key is also one of the keys that are used more frequently on the computer keyboard. When using Enter key, you should pay attention to: Don't slam it hard.

the ASCII code of carriage return

is "xd" in hexadecimal

and "13" in decimal

which can be represented by \r in some languages.

carriage returns are handled differently in different operating systems:

in Unix/Linux systems, line breaks are represented by \n one character,

in Windows systems, they are represented by \n\r two characters.

virtual key: Enter key is vk_Return = $D; The corresponding Char is also #13
