Interface Question - Pose Controls

billyrosco

I want to bend my character's left hand.

Sometimes the pose control sliders, such as BEND in this case, appear as a circle rather than the bar. It seems to me that this indicates that tampering with the slider in this state would give problematic results or create undesirable movement. 

Why does this happen? What does it mean?

It's a quick reference icon, similiar to those with a character picture for character presets.

Circle=Rotation=moving in a circle

Cross=Translation=moving in a line.
