Displays skeleton type, IK handles or constraints.
All Windows – The display of the skeletons are toggled in all windows.
Current Window – The display of the skeletons are only toggled in the current window. The current window is the one that has three asterisks (***) in its title bar. To make a window current, click its title bar or in the window itself.
If a joint in a skeleton is constrained to another object, a line is drawn between the skeleton joint and the rotate pivot point of the object to which it is constrained. A skeleton joint’s constraints are displayed only if the skeleton joint is active.
Click to toggle ON (indicated by a check mark) or OFF. If toggled OFF, no constraints are displayed in the window(s).
