Can't find toggle pixel aspect ratio correction button to draw a circle?

[meganchi]

I'm trying to follow a tutorial from linkedin learning for drawing a circle in After Effects. I am on M1 mac running the 2022 intel version for this software. How in the world do a draw a cirle? In the tutorial they show a button in the composition window after using the ellipse tool to select "Toggle Pixel Aspect Ratio Correction" to change the ellipse to a perfect circle. Help? I don't see that icon and can't find it in any menus offhand.

The Pixel Aspect Ratio correction icon/button was removed from the Comp Panel not too long ago. You can still enable/disable it within each composition's hamburger menu.

Toggling the PAR correction may not be what you're looking for unless you're working with non-square pixels. If you want a circle without PAR being involved, hold down the Shift key before you start dragging the with the Ellipse tool and the ellipse will be constrained to make a circle.

If you're on the current AE Beta, you can also Shift+double-click the Ellipse tool in the toolbar to create a circle that fills the comp.
