Undo Symbol

Behavioral Issues in the Use of Interactive Systems, a 1976 research report by Lance A. Miller and John C. Thomas of IBM, noted that “It would be quite useful to permit users to ‘take back’ at least the immediately preceding command (by issuing some special ‘undo’ command).” The programmers at the Xerox PARC research center assigned the keyboard shortcut Ctrl-Z to the undo command, which became a crucial feature of text editors and word processors in the personal computer era. - Wikipedia
