A data processing system includes an operating system, a graphical user interface and a plurality of applications programs. The graphical user interface generates a window relating to an executing application programs. Menu items relating to an application program may be represented by an icon. A selected group of objects is defined over a portion of the menu and represented by a metaphor. The graphic metaphor, here an icon ring is displayed on a display device. The icon ring is evocative of an ordered arrangement of items of the selected group, includes the icon for a particular object open to selection, and is subject to direct manipulation for reordering of the underlying selected group.
