Larry Tesler created the concept of cut, copy, paste, and undo for human-computer interaction while working at Xerox PARC to control text editing.During the development of the Macintosh it was decided that the cut, paste, copy and undo would be used frequently and assigned them to the ⌘-Z (Undo), ⌘-X (Cut), ⌘-C (Copy), and ⌘-V (Paste).
A Control key (marked "Ctrl") on a Windows keyboard next to one style of a Windows key, followed in turn by an Alt key The rarely used ISO keyboard symbol for "Control". In computing, a Control keyCtrl is a modifier key which, when pressed in conjunction with another key, performs a special operation (for example, Ctrl+C).

Standard keyboards transmit this code when the Ctrl and Z keys are pressed simultaneously (Ctrl+Z, often documented by convention as ^Z). [1] Unicode inherits this character from ASCII, but recommends that the replacement character ( , U+FFFD) be used instead to represent un-decodable inputs, when the output encoding is compatible with it.
Ctrl-C (in older Unixes, DEL) sends an INT signal ("interrupt", SIGINT); by default, this causes the process to terminate. Ctrl-Z sends a TSTP signal ("terminal stop", SIGTSTP); by default, this causes the process to suspend execution. [4] Ctrl-\ sends a QUIT signal ; by default, this causes the process to terminate and dump core.
