The keys Control-Alt-Delete highlighted on a QWERTY keyboard.
Control-Alt-Delete (often abbreviated to Ctrl-Alt-Del, also known as the "three-finger salute")[1][2][3][4][5] is a computer keyboard command on IBM PC compatible systems that can be used to reboot the computer, and summon the task manager or Windows Security in more recent versions of the Microsoft Windows operating system. It is invoked by pressing the Delete key while holding the Control and Alt keys: Ctrl+Alt+Delete. It forces a soft reboot, brings up the task manager (on Windows and BeOS) or a jump to ROM monitor. In most X desktops it brings up the Logout dialog. These keys are sometimes referred to in computer manuals as interrupt keys, since they are often used to interrupt the operation of a malfunctioning program.
