Time IPO?

I’ve constrained an object to move along a path, and I’d like to be able to affect its speed and other behavior along the path. I understand that it should be done with a Time IPO, but I can’t seem to figure out how to get Blender to display that IPO.
I assume it’s an IPO associated with the object that’s moving (constrained)?

You actually want to use the Speed IPO in the Path context of the IPO window. If you add Curve >> Path it’ll display automatically. For other Curve types you add it with Ctrl-LMB.

AH! Got it! Thank you!
I was looking in the IPOs associated with the constrained object, thinking of it as a function of the constraint. Instead, it’s a property of the path, it seems.
