How to mirror the riggify armature?

Hi, I am working on a walk cycle animation, the thing is I have completed a part of the animation where his dominant right foot extends, has contact with the ground, pushes off, trades dominance with the other foot, other foot extends, then has contact with the ground. This all happens initially on his left side but now that his right foot is dominant, I want to mirror what just happened on his right side.

Basically is there way to mirror the armature position to his other side so I don’t have to repeat this process for his right side? For example if his left arm is vertical and his right arm his horizontal is there a button to mirror this so that his left arm is horizontal and his right arm is vertical? Sorry if this was a little confusing. Thanks.
