The Attach Controls dialog box lets you attach saved tracks to the Block controller.

IK controller
The IK controller works on a bones system for controlling the bone objects of an IK (inverse kinematics)
system. The IK controller includes many different rollouts for defining joint constraints and other parameters.

Cross-Ref
Find out more about the IK controller in Chapter 37, “Understanding Rigging and Working with Bones.”

Master Point controller
The Master Point controller controls the transforms of any point or vertex subobject selections. The Master
Point controller is a controller that you can select and add, but instead it gets added as a track to an object
whose subobjects are transformed. Subtracks under this track are listed for each subobject. The keys in the
Master track are colored green.
Right-clicking a green master key opens the Master Track Key Info dialog box, shown in Figure 34.33.
This dialog box shows the Key number with arrows for selecting the previous or next key, a Time field that
displays the current frame number, and a list of all the vertices. Selecting a vertex from the list displays its
parameters at the bottom of the dialog box.
