Editing Transition Attach Points

Place the cursor over an attach point until it changes to a small circle. Click and drag the mouse to move the attach point; release to drop the attach point. You can edit both the source and destination attach points of a transition.

The appearance of the transition changes from a solid to a dashed line when editing a destination attach point. Once you attach the transition to a destination, the dashed line changes to a solid line. The appearance of the transition changes to a default transition when editing a source attach point.

To delete a transition, select it and choose Cut (Ctrl+X) from the Edit or any shortcut menu, or press the Delete key.
