To cut or copy a transition, right-click it and select the desired operation from the popup context menu. Alternatively, you can select it in the Event Flow panel, and then press the Control X and Control C shortcut keys, or click the or buttons on the Event Modeler toolbar, respectively. This is the same as cutting or copying the transition's associated rule from the Rules panel.

Then you can press Control V, or click the button on the Event Modeler toolbar. The newly pasted rule is renamed to Copy of its_previous_name if there is still a rule with the same name within that state. For example, if you copy a transition or rule and then paste it back into the same state, the newly pasted one will be renamed. The transition's destination state will be preserved provided that the destination state still exists. If not, it will revert to continue.
