The navigator tree is organized much like the hierarchy of a file system, where you can expand branches that begin with a plus sign (+) to further sub-branches until you find your component of interest. Sub-branches appear indented below the branches from which they are expanded. Branches that are expanded are preceded by a minus sign (-). You can expand no further when a branch displays neither a plus nor minus sign. You can use either your mouse or the arrow keys on your keyboard to expand or collapse the navigator tree.
The Navigator window also contains a toolbar that you can use to perform actions within the Navigator window. See: Navigator Toolbar.
