Let's imagine you have a large number of animated objects. Correspondingly, the choreographer window shows you a large number of time lines. In order to control the timing of all the choreographs through a single time line:
1. Click the tool to create a choreographer object.
2. Move all the animated objects inside the newly created choreography object.
3. Make sure the choreography object is selected and open the Choreographer window. Now you can see only one time line through which you can control all the sub time lines.
