Selection: Single Graph or single Node
Effect: Allows to create a graph path of arbitrary length by navigating the classes and references of the imported packages. This is done by unfolding a dynamic menu structure on demand. There are several different menu types: The Reference Selection offers all known references owned by the selected type. If the menu is shown for a node, this is done for the node's type. The Subclass Selection shows all classes that are compatible with the type of a selected reference. If the graph contains nodes whose type is one of those classes the menu will contain a section to connect the path to an existing node. If either a subclass or an existing node are selected the path may be created by selecting "Create" or "Connect". Also the path may be continued by selecting the corresponding ".. and expand" item. If the menu is opened for a graph an initial element has to be selected first. For this purpose there is an additional menu that allows selecting an imported package and one of its contained classes. The expansion of the path can now be done in the same manner as if the menu was initialized for an existing node.
