Im using Unity 4.3.2f1 at windows

and Im learning about mecanim from here → 1

at time 29:06 the video says about curves…
why I cant see them ?? is it pro feature ??

how can I see the curve list in animation if I dont use the pro Unity ??!

Its right there in above image only, the last option is curves, that is a dropdown kind of thing just click on either the triangle or the the name you will be able to see the curves.
