I tried this out on just a basic advanced biped rig. In adjust mode - components, I can adjust the chest controller, and this then moves all of the components that are controlled by it (ie shoulder, arms etc.). I thought I could adjust this up without moving my shoulders and arms which I spent a lot of time getting into place. When I switch to adjust controllers, the chest controller is not visible. Not sure why that is, but I'm sure it's related to some simple stuff that I just don't do much of. The 7 key is working when It's not a controller.
