Switch child and parent nodes
In the Report Structure, you have two nodes in a parent-child hierarchy. You can make the child the parent, and the parent the child.
While holding the ALT key, drag the child and drop on to the parent.
This example starts with the WordBox being a child of the Orders_orderid trigger node:

Figure: WordBox is child of Orders_orderid trigger

While holding the ALT key, click on WordBox, then drag and drop it on top of Orders_orderid.

Figure: Orders_orderid trigger is child of WordBox

The two nodes have effectively switched places.
