You can quickly determine where a WSDL component is used in the WSDL file.
In the WSDL view, right-click the component and choose Find Usages.
The Usages window opens in the lower part of the IDE. The window has three parts:
Toolbar. The toolbar buttons let you refresh information in the window, expand and collapse nodes in the tree pane, and cycle through the found usages.
Tree pane. The tree pane contains nodes for the results of the query.
Graph pane. The graph pane shows a graphical representation of the results.
To zoom out, right-click in the graphic and drag up. To zoom in, right-click in the graphic and drag down.
To pan, click and drag in any direction.
To drag a node, click and drag the node.
