ASCII Character ^Caret - circumflex
Caret is the name used familiarly for the character ^, provided on most QWERTY keyboards by typing ⇧ Shift+6. The symbol has a variety of uses in programming and mathematics. The name "caret" arose from its visual similarity to the original proofreader's caret, a mark used in proofreading to indicate where a punctuation mark, word, or phrase should be inserted into a document. The formal ASCII standard (X3.64.1977) calls it a "circumflex". The incorporation of the circumflex symbol into ASCII is a consequence of this prior existence on typewriters.
