Thanks @mikel
I did read that. Maybe I'm not understanding. I don't want my animation to scrub backwards – even before the end of the animation has been reached.
For example, here the parallax works going right but not left.

From my understanding of toggleActions, you have to get to one of the toggle places (e.g. the end) before you can trigger an action. Put it another way, I want to scrub forwards only, not backwards
