Abstract: A user may easily switch between multiple open windows in multiple applications on a computer desktop. A visual indicator is provided on an application button. The indicator is linked to a list of open windows within an application represented by the application button. By interacting with the visual indicator, a desired selection from the list of open windows can be surfaced. The visual indicator may comprise an arrow positioned within the application button. Interaction with the visual indicator may comprise positioning a pointer of a pointing device over the visual indicator on the application button. A user then clicks and holds on the visual indicator with the pointing device. A pop-up menu is surfaced containing the list of open windows within the application represented by the application button. By releasing the pointing device over a desired selection on the list of open windows, the desired selection is presented to the user.
