830 Chapter 12 Using Shapes and Masks
Adding more control points does not immediately change a Bezier shape, unless you
drag Bezier curve points as you create them.
Adding more control points to a B-Spline shape, on the other hand, nearly always
changes its shape.
To append control points to the end of an open shape:
1 Select an open shape with the Adjust Control Points tool.
2 Option-click anywhere outside of the shape to add new control points to the end of
the shape.
3 Option-click the first point in the shape to close it (or press C).
If a shape has more control points than are necessary, you can delete points from it to
make it easier to edit. This can be helpful if you animate the shape later on.

Warning: In general, do not add control points to a shape that’s already been
animated. If you add points to a shape that already has keyframes applied to its
Shape Animation parameter in the Keyframe Editor, the new point does not follow
the currently keyframed path.
