Expanding Nodes

Nodes that are expandable appear with a thicker box border. Double-clicking these nodes displays the child and parent nodes (do the same thing by choosing Expand Both).

To expand nodes:

1. Select one or more nodes by holding down the Shift key and clicking on each node.

2. From the Nodes menu, choose one of the Expand commands, or double-click on the node to expand a single node in both directions.
