Touchmaster Five with carriage return lever at left. Originally, the term "carriage return" referred to a mechanism or lever on a typewriter.For machines where the type element was fixed and the paper held in a moving carriage, this lever was on the left attached to the moving carriage, and operated after typing a line of text to cause the carriage to return to the far right so the type ...
5 Carriage Return (accompanied by line feed) is used as "end of line" character by Windows, DOS, and most minicomputers other than Unix- / Linux-based systems 6 Control-O has been the "discard output" key.
The carriage return character (CR), when sent to such a device, causes it to put the character at the edge of the paper at which writing begins (it may, or may not, also move the printing position to the next line). The line feed character (LF/NL) causes the device to put the printing position on the next line.
U+000D CARRIAGE RETURN (CR) (used in some line-breaking conventions) U+0085 NEXT LINE (NEL) (sometimes used as a line break in text transcoded from EBCDIC) Unicode only specifies semantics for U+0009—U+000D, U+001C—U+001F, and U+0085 (the ASCII format effectors except for BS, plus the ASCII information separators and the C1 NEL).
Form feed is a page-breaking ASCII control character. It directs the printer to eject the current page and to continue printing at the top of another. Often, it will also cause a carriage return. The form feed character code is defined as 12 (0xC in hexadecimal), and may be represented as Ctrl+L or ^L.
In Unicode, characters can have a unique name. A character can also have one or more alias names. An alias name can be an abbreviation, a C0 or C1 control name, a correction, an alternate name or a figment. An alias too is unique over all names and aliases, and therefore identifying.
Examples of control characters include carriage return and tab as well as other instructions to printers or other devices that display or otherwise process text. Characters are typically combined into strings. Historically, the term character was used to denote a specific number of contiguous bits.
ASA control characters are simple printing command characters used to control the movement of paper through line printers. These commands are presented as special characters in the first column of each text line to be printed, and affect how the paper is advanced before the line is printed. The remainder of the line is printed starting in the ...
