In computing, control-\ is a control character in ASCII code, also known as the file separator or field separator (FS) character. It is generated by pressing the \ key while holding down the Ctrl key on a computer keyboard.
Under most UNIX-based operating systems control-\ is used to terminate a running process from a command shell and have it produce a memory core dump by sending it a SIGQUIT signal.[1]
As a character that can be easily typed on most keyboards, but with no standardized meaning, control-\ is often used as a keyboard shortcut in different graphical user interfaces, with various unrelated effects. For instance, some versions of Windows File Manager use it to de-select all selected files.[2] In Adobe InDesign, it has been used to mark a point in a line of text as the starting position of a hanging indent.[3]
