Methods and apparatuses for controlling application programs are described. A first item and a docking interface having a second item are displayed on a screen space. A selection of the first item is received. A proxy of the first item is positioned over the second item. Next, a window is displayed in response positioning. An application is executing to display the window. In another embodiment, synchronizing a first docking interface on a first screen space of a first machine to a second docking interface on a second screen space of a second machine is performed. The first docking interface has an item that identifies a first application supported by the first machine and the second docking interface has another item that identifies a second application supported by the second machine.
