Techopedia explains Caret

The caret was historically introduced in handwritten form as a proofreading mark. It was used to indicate a word, phrase or punctuation that needs to be inserted at a certain location in a document. In the ASCII character set, the value 5E (hexadecimal) is reserved for the caret. Early computer systems such as microcomputers and mainframes made use of the caret character. However, with the technology advance in computer monitors, the caret character was less required and was left for other requirements. It was also difficult to accommodate above a letter due to the larger appearance.

The caret is used in various programming languages to signify the XOR operator, control characters and string concatenation. It is still used in regular expressions, to mark the beginning of a line or string. Pascal makes use of caret for pointer declarations. The programming language Go uses the caret as a bitwise NOT operator. The caret key is available in all standard U.S. qwerty keyboards.
