What the Clintons do:
CONTROL, ALT, DELETE
When the operating system seems to hang suspended while waiting for an application program to continue, a user is also left without a way to regain control of the system. The Ctrl-Alt-Delete key combination allows the user to terminate the "hung" application and, if that doesn't work, to reboot the system. The system can also be restarted using the mouse to select Start-->Turn Off the System-->Restart. However, Ctrl-Alt-Delete sometimes works when the menu option doesn't.
