Mecanim Tutorial - Anim Curves Missing?

Hi guys I’m just looking through the mecanim tutorial:

However, around 29mins the tutorial starts talking about animation curves (specifically to change the size of a collider during a jump).

This doesn’t appear in Unity when I follow the same steps as the screenshot shows (it’s supposed to be below Transform mask according to tutorial). What am I missing? Using Unity Free BTW.

Thanks

Ah…curves only seem to be a Pro feature?
