Changing property keys
Property manipulation provides the finest level of control over object attributes in your animation. By manipulating properties, you can change how individual aspects of a given object animate.
You can move property keys from one frame to another, and add or delete property keys.
For example, consider an animation in which a geometric object moves across the screen over the first 10 frames, and a text object changes color from frame 10 to 20. If you want to overlap the color change with the movement, drag the text object’s fill color property key from frame 10 to an earlier frame.
When manipulating properties, you can also add and delete keys.
