In the earliest days, the typing position on the typewriter was fixed, and the home-and-line-break wrench was used to move the carriage carrying the paper roller to the far right. , so that the printing position is aligned with the beginning of a line, and at the same time, the roller is rotated to change to the next line. Later, when the typewriter drum no longer moved laterally, the carriage carrying the printing head moved back to the starting position of the line.

Carriage Return The term "return" is a control character of the Baudot Code used by teleprinters (TTY). It means returning to the beginning of a line of words, but does not mean line break (or line break). enter the queue).

The home key first appeared on Smith Corona's electric typewriters in 1960. This key is usually labeled "Carriage Return" or "Return". To help non-English speaking users learn to type, typewriters published later were often marked with a "↵" symbol.

Regarding the origin of the "Enter key", we have to start with the mechanical English typewriter. On the mechanical English typewriter, there is a part called the "character carriage". Every time a character is typed (originally a word, but I personally think it should be a character here), the "character carriage" advances one frame. When a line of characters is filled, the typist has to push the "cart" to the starting position. At this time, the type machine will respond with two actions: one is that the "cart" is returned to its position, and the other is that the roller rolls up a line to start. Enter the next line. This action of pushing the "cart" is called "Enter". Later, on electric English typewriters, people added a key that directly acted as a "carriage return" key. This new key is called the "Enter key".

On computer keyboards, the words "CR" and "RETURN" were once used on the "Enter key", but were later unified as "Enter".
