Sort of a newbie to After Effects CC 12.1.0. It was my understanding from the guide that when I click on the pen tool, I'd get a choice of pen types; regular pen, eliptical (oval), and so on. But I just get the pen tool. I know the square box tool is next to the pen tool on the menu bar, but where is the eliptical tool? That's it (so far). Thanks!
Hold your mouse button down on the Rectangle tool and you'll be presented with other shape choices. Or just press Q to toggle between them.
Strongly recommend you follow Todd Kopriva's guide "Getting Started With After Effects".
