The Edit Triggering Events or Events command, accessed on the Diagram ribbon, allows you to manipulate the collection of events that trigger the current transition. The command opens a target window on the triggered by relation from which you can add or remove events as desired.
NOTE: |
If you simply wish to add an event to a transition, often this can be accomplished most quickly by dragging and dropping from the diagram Toolbox - either by dragging the Events construct from the Constructs tab or by dragging the specific event to be added from the Key Entities tab. |
