A similar mark has a variety of unrelated uses in programming, mathematics and other contexts. The symbol was included in typewriter and computer keyboards so that circumflex accents could be overprinted on letters (as in ). This facility is not provided as standard on typical US keyboard settings and so the character became reused in computer languages for many other purposes. The misnomer "caret" is frequently applied to the circumflex symbol in that context, because of its similarity to the proofreading mark for insertion. This page will call this symbol a "circumflex" to distinguish it from a true caret. This circumflex is not to be confused with other chevron-shaped characters, such as the circumflex accent, the turned v or the logical AND, which may occasionally be called carets.
