I am looking in the CK for the animations but I can't find them. Any lists available or is it hidden somewhere?

In previous games you could click Gameplay > Animations, but in this one it's just a list that references the behavior graph. It appears you can't preview them, which is a huge bummer.

Hopefully you can and I'm just missing something...

Well that was enough to help me find a bunch of animations I can try, thanks!

I found a way. Once you declare an idle property in your script you can go to properties where you auto fill and browse them there.

That would hardly ever work. Idle Animations use conditions, and will only work if the Actpr is meeting those conditions. I would use http://www.creationkit.com/SendAnimationEvent_-_Debug. It doesn't use conditions, and can even play attacking events.
