A method referred to as x-ray browsing for allowing a user to browse through windows on their desktop is provided. Aspects of the invention include responsive to a command, making a first window the window in focus on the display screen and changing the relative opacities between a content portion of the first window and a content portion of the second window. By controlling the opacities a single window can be made opaque while the remaining windows can be made transparent to allow a user to successively navigate among open windows.
