[controller type] Determines the controller type to assign to each track within
the animation layer.
■ Duplicate the Active Controller Type The new layer's controller type
becomes the same as the one from the active layer, on a per-track basis.
For example, if a track in the active layer has a Noise controller, adding a
new layer copies that controller type.
■ Use Default Controller Type When chosen, the new layer's controller
does not take into account the active layer's controller type and instead
uses the original track's type.

Limit
The Limit controller lets you specify upper and lower limits to available
controller values, thus restricting the potential value range of the controlled
track. For example, in a character rig you could use this to restrict rotation on
finger joints so the fingers can't bend backward. Basically, once a track is
limited, and the limit is active, you can't set a value for the track beyond the
limit. You can apply a Limit controller to any other type of controller; the
limited controller (that is, the original controller) then appears as a child of
the Limit controller in the Track View hierarchy.
The Limit controller lets you specify upper and lower limits to available
controller values, thus restricting the potential value range of the controlled
track. For example, in a mechanical assembly you could use this to restrict
rotation on a part so that it doesn't rotate beyond its standard range of motion.
Basically, once a track is limited, and the limit is active, you can't set a value
for the track beyond the limit. You can apply a Limit controller to any other

Because the Limit controller doesn't change the original controller, you can
easily switch back and forth between the original and the limited animation
by toggling the limits. But if you
collapse on page 3549 the Limit controller, the
result is the limited animation, and the original animation is no longer
available.
