changes to the shape’s control points.
In the Keyframe Editor (and also in the Timeline, if the Show/Hide Keyframes button is turned
on), a keyframe appears for each adjustment you make at a new frame.
Note: Adjusting a shape while the playhead is on an existing keyframe adjusts the shape at
that keyframe.
4 Continue advancing frames and making changes.
Every time you make a change to the shape at a new frame, you create a keyframe in that
shape’s Shape Animation parameter.
5 When you are done animating the shape, disable Record.
