Constant Velocity When on, interpolates values between the key and the
next one so that the object moves at a constant velocity across that curve
segment. Available only with certain controller types, such as Bezier.
Free Handle Used for automatically updating the length of the tangent handle.
When this is turned off, the length of the tangent is at a fixed percentage from
its neighboring key. As you move a key, the handles adjust to stay the same
percentage away from the neighboring keys. When this is turned on, the
handle lengths are based on time lengths.

Controllers, like
constraints on page 3287, handle the animation tasks in a scene,
including:
■ Storing animation key values
■ Storing procedural animation settings
■ Interpolating between animation key values
An object or parameter doesn't receive a controller until you animate it. As
soon as you change an animatable parameter with Auto Key on, or
add a key
on page 3617 in Track View - Dope Sheet on page 3503, the software assigns a
controller to the parameter. The software chooses a default type for the
controller, depending on the animation. You can change the default controller
to another type.
The animation controllers are organized in the following categories:
■ Float controllers: for animating floating-point values
■ Point3 controllers: for animating three-component values such as colors
or 3D points
■ Position controllers: for animating positions of objects and selection sets
