Redexes that are destroyed (or created) by prior contractions in this process are not reduced, thus if single applications of the rule terminate, so does its simultaneous application. Right-clicking does /not/ select the rule.

--- - Right-click on a node of the graph to apply the selected rewriting rule at that position. You know before whether it is a applicable, since all redexes in the graph with respect to the selected rule are marked red. Right-clicking on a non-redexs node has no effect. The layouting stops while the right mouse-button is pressed.
