Thanks Bryan. I got it.

Assuming you have the production
 
    tree: node1 node2 node3;
 
Replace it with something like the following.  The syntax may not be quite right, but it's close...
 
    tree!: node1 node2 node3 { #( #[TREE,"TREE"], #node1, #node3, #node2); }
 
 
How can i shift the position of node2 to node3?
