ABSTRACT:
This disclosure describes, generally, tools for navigation of tree structures. For example, a software application comprising a user interface for allowing a user to navigate a tree structure is described. The user interface comprises a graphical element including the tree structure. The tree structure comprises multiple nodes which represent a hierarchical view of data within the structure. One of the nodes is set as the active node. The computer software application also includes a storage element to store a list of previous active nodes. The graphical element is in conjunction with a first navigational element configured to step backward through the list of previous active nodes, and to set the stepped to node as the active node. The graphical element is further in conjunction with a second navigational element configured to step forward through the list of previous active nodes, and to set the stepped to node as the active node.
