Path handles: how to access?

I can't find any information about how to access a path's handles to smooth it. In Animate:

1. I created a polyline

2. I selected an actor

3. I clicked Create from Line in Animate and selected the polyline as directed. The actor moved to the end of the line.

Now I want to smooth the actor's path along that polyline because the polyline is comprised of straight lines. How do I get the actor's path to show the handles to allow smoothing as a bezier curve would? I've done this before but can't remember what to do and Composer's Help system is useless.

Thanks, Jeff
