how does keynote define an "object" in a drawing
When I create a drawing in Keynote with my Apple Pencil, the software seems to spontaneously create objects (as delineated by invisible boxes) from parts of the drawing. How does Keynote decide that, and how can I change it. These objects form the units for animation. If I want to animate parts of the drawing separately, how do override the grouping created automatically.
