Animation mirroring

coolkidslike

Hi guys I was wondering is there any way I could mirror the motion? ( In my case I'm trying to mirror the hand motion, like the same value with both hands and only have to control one hand) 

I'm completely new to Daz so a bit confused. 

Additionally, May I know how can I modify posing values more easily? 

seems like no keyframe is made when I make adjustments and a bit hard to delicately modify. Is there a way to see the value has already been made?

I'm doing an animation with Daz and it's convenient but seems like I am not using 100percent out of it. 

Thanks!
