In 1973, ECMA-35 and ISO 2022 [18] attempted to define a method so an 8-bit "extended ASCII" code could be converted to a corresponding 7-bit code, and vice versa. [19] In a 7-bit environment, the Shift Out would change the meaning of the 96 bytes 0x20 through 0x7F [a] [21] (i.e. all but the C0 control codes), to be the characters that an 8-bit environment would print if it used the same code ...
For example, the key labelled "Backspace" typically produces code 8, "Tab" code 9, "Enter" or "Return" code 13 (though some keyboards might produce code 10 for "Enter"). Many keyboards include keys that do not correspond to any ASCII printable or control character, for example cursor control arrows and word processing functions.

Video terminals designed to replace the teletype then had to place a key that produced this code where Backspace would be expected, in particular in products from Digital Equipment Corporation. On VT100 compatible terminals, this is the character generated by the key labeled Delete .
There are five possible reasons to assign an alias name to a code point. [1] A character can have multiple aliases: for example U+0008 <control-0008> has control alias BACKSPACE and abbreviation alias BS. 1. Abbreviation Commonly occurring abbreviations (or acronyms) for control codes, format characters, spaces, and variation selectors.
An early typewriter with a backspacer[sic] key.(Blickensderfer Model 7)Although the term "backspace" is the traditional name of the key which steps the carriage back and/or [note 3] deletes the previous character, typically to the left of the cursor, the actual key may be labeled in a variety of ways, for example delete, [1] erase, [note 4] or with a left pointing arrow.

The Patriots took control of the 2025 NFL draft's No. 1 pick after the Giants beat the Colts in Week 17. Who will go with the first overall pick?
The \n escape sequence allows for shorter code by specifying the newline in the string literal, and for faster runtime by eliminating the text formatting operation. Also, the compiler can map the escape sequence to a character encoding system other than ASCII and thus make the code more portable.
