Swivel angle manipulator.
When you move the mouse over the manipulator, it turns red. At this point,
you can drag the manipulator to change the swivel angle. The Auto Key button
can be active while you do this.
You can also animate the swivel angle by using a target object. Pick an object
for the target, then animating the object will animate the swivel angle.
The swivel angle manipulator is a standard
plane angle manipulator on page
2640. The HI Solver has its own controls for displaying this manipulator. These
are on the IK Display Options rollout on page 3416.
