An ASCII control or metacharacter (#27, ^]) with its own key on most keyboards, intended originally to signify escape (v) (sense 1). While it has been put to a number of different uses over the decades, it is still often used to pause or terminate a program or process. Frequently called Meta in some programs, notably emacs, where it is a common command prefix.
To pause a running program and return control temporarily to the operating system, usually in order to run some other program. In Unix, the exclamation point (ASCII #33, !, pronounced "bang") is an escape character that can be used in most programs to accomplish this. To cancel the default ( meta-)interpretation of the following character in a string and interpret it literally instead. Thus, while the unescaped (meta)expression " ." matches any character, the regular expression "\." matches a literal period or full stop character only, because it is escaped by the preceding "\".
From Extensible Markup Language (XML) 1.1 ( 2004-02-04) Entity and character references MAY both be used to escape the left angle bracket, ampersand, and other delimiters. A set of general entities (amp, lt, gt, apos, quot) is specified for this purpose. Numeric character references MAY also be used; they are expanded immediately when recognized and MUST be treated as character data, so the numeric character references and &MAY be used to escape and & when they occur in character data.
Various programs and windows can be closed by one of these: Enter, Escape, q, Alt+q, Alt+F4, Control+q The + means you hold the first while tapping the second. The comma isn't part of the command. ALPHABET
Using escape on a character or a string of characters is a way to change how it is interpreted. This can take away its special meaning, as in shell quoting; or it can add special meaning, as in terminal escape sequences.

To escape a character in C is to precede it with a backslash, indicating to the compiler that it should be treated literally rather than as a syntactical element. In other words, an escaped character is always mentioned rather than used.
(1) (v.) To divest a special character of its special meaning by preceding it with a backslash (\) character. For example, the UNIXÂ® shell interprets ? to represent any single character, but a \? (an â€œescapedâ€ question mark) is interpreted to be just a question-mark character.(2) (n.) The Esc key on the keyboard.(3) (n.) The escape character that is generated by pressing the Esc key.
in the shell context, is the action of surrounding some string between quotes to prevent the shell from interpreting that string. For example, when you need to use spaces in some command line and pipe the results to some other command you have to put the first command between quotes ("escape" the command) otherwise the shell will interpret it incorrectly and won't work as expected.
(1) (vi) The Esc key, used to terminate insert mode, or an incomplete vi command; (2) To prevent a character from having its normal interpretation by a program by preceding it with the escape character (usually \, the backslash); for example in a regular expression, to search for a literal character that has a special meaning in a regular expression, it must be escaped; as a specific example, to search for a period (.), you must type it escaped as \.
The option a character has the first time he is attacked by another character. In order to escape he must have a higher speed stat than his opponent(s). If he escapes his attackers must leave him alone for 15 minutes.
When you escape a character or a string of characters, you change the way it is interpreted. Escaping something can take away its special meaning, as in shell quoting ( 8.14)- or can add special meaning, as in terminal escape sequences ( 5.8).
