    摘要: A method for assisting window selection in a graphical user interface determines one or more current top-level windows to be displayed to a user for selection by the user. The user is then able to select a particular window of the one or more windows being displayed. In some embodiments, the one or more current top-level windows are displayed as translucent windows. Additionally, in some embodiments, a user is able to cycle through multiple sets of one or more windows in order to locate a particular window.
