A control window for navigating and implementing menu selections in a multiple level hierarchical menu is provided having a first zone displaying a list of the selection levels and a second zone displaying a list of the selection options within a selection level. The second zone is refreshed with selections for another selection level in the menu hierarchy in response to a user implementation or registration of a selection option at the originally displayed selection level. Preset default settings in all selection levels permit the user to implement a 'fast path' hierarchical menu selection.

A method for selectively displaying portions of complex graphics including trees, directed acyclic graphics, and cyclic graphics on a computer display screen while retaining information concerning all nodes interconnections so that graphic information can be correctly recalled as required. Relevant interconnection information concerning a node or nodes to be collapsed or expanded are collected and analyzed. Elements of that interconnect information are displayed while retaining all information needed to display any obscured or hidden portions of the graphic when required. All nodes connected to each selected node are identified and each identified node is assigned to a first set of nodes. A second set of nodes is created that is initially empty. Each node is removed from the first set of nodes and assigned to the second set of nodes. All nodes connected to a remove node are identified and compared to nodes already stored in the first set of nodes. When nodes are not found in the first set of nodes, the nodes are added to the second set of nodes. This process of removing and identifying connected nodes are repeated until the first set of nodes is empty.

A user interface system is used for accessing and performing window management operations. A control window containing icons linked to product windows. Each icon in the control window is also capable of projecting a miniature window dynamically linked in terms of content and parameters to the actual information represented by the icon. Window management operations, such as moving, sizing, restoring, and closing, performed on either the iconic or miniature window representations in the control window are transmitted directly to the contents of the represented windows and implemented, whether these windows are opened or closed at the time that the operations are performed.
