Windows Keyboard Shortcuts. Graphical interfaces are great. It is fun to move a mouse around and click on icons and things to get things done.

Of course, if he points the gun at you, you are likely going to give up the password anyway; but, hey. Nothing is perfect. There are many Win key commands. Try some.
