The primary purpose of the traversal frame is the ability to explore the structure of instance nodes. The functionality of the traversal frame is very limited. Only operations concerning insertion and propagation of evidence are included. Any operations performed in the traversal frame is also performed on the main network (from which the traversal frame was invoked). By right-clicking on a node in the traversal frame, monitor windows for that node can be opened in the main network and in the traversal frame (See figure 1).
