Following Edges

When working with very large graphs where the nodes are connected by long edges it is useful to navigate through the graph by taking advantage of the graph structure. This is done by following edges through the graph. The Follow Edge item of the Position menu in the menu line offers this navigation method; alternative: press the e key.    

The Follow Edge operation works like this:

   
Follow Edge Dialog Box - History List of Nodes

A history is implemented via the Follow Edge operation so that the path through the graph can be traced back. Pressing the h key during the Follow Edge   operation causes the history dialog box to appear (see Figure 5) and shows all the nodes encountered during the Follow Edge operation.

The list of nodes is shown as a list of the following node attributes:

The Follow Edge Dialog Box is used as follows:
