full screen mode

hi guys, a typical new beginner question I suppose.
I use to fly FSX in full screen mode but in a previous thread I knew I can run not only in that way so I mean in a window.
how can I do that and how can I switch between full and not acreen mode?
thanks for helping! gianluca

By pressing the Alt + Enter key's you can switch between windowed and full screen modes.

thanks kd
