Learn how to add an action into the animation timeline.
In the Animation workspace, select a storyboard.
Drag the playhead to the desired point on the timeline.
Use a command to change the scene in the graphic window.
For example: Select a component, click the Transform command from the ribbon, then move the object 10 cm along the X axis. Press OK, and you can see an action appear on the timeline documenting that move.
After you confirm a scene change (click OK in the command dialog), the corresponding action is automatically added into the timeline.
