<p>A navigation system for a hierarchy of objects displayed by a computing system are rapidly navigated first by an automatic explosion module for exploding a displayed node of the hierarchy in response to a first characteristic stroke by a pointer control device while the pointer is within the boundary of the displayed node. In addition, an implosion module implodes nodes branching from a displayed node of the hierarchy in response to a second characteristic stroke by the pointer control device while the pointer is within the boundary of the displayed node. The first characteristic stroke by the pointer control device is movement of the pointer controlled by the pointer control device within the boundaries of the displayed node. The second characteristic stroke by the pointer control device is a mouse click while the pointer is within the boundaries of the displayed node or object. A keystroke module sets the level of further explosion of the node when the displayed node is exploded by the explosion module.</p> |
