Ctrl-V

In computing, Control-V is a control character in ASCII code, also known as the synchronous idle (SYN) character. It is generated by pressing the V key while holding down the Ctrl key on a computer keyboard.

In many GUI environments, including Microsoft Windows and most desktop environments based on the X Window System, and in applications such as word processing software running in those environments, control-V can be used to paste text or other content (if supported) from the clipboard at the current cursor position. Control-V was one of a handful of keyboard sequences chosen by the program designers at Xerox PARC to control text editing.
