I have downloaded all of the fundamentals of animation source files. I am now working on the Arcs of Motion section. When I get to part II you describe using the various SquashControls (1&2) etc to modify the shape of the cube. However, when I drag the triangular controls as you do in the video, NOTHING HAPPENS. I can't make it perform any sort of deformation. I went to the next lesson, Follow-Through, the same thing doesn't happen. The controls seem totally independent of the cube.
How do I find what the Gauges are supposed to be connected to and enable them?
I am using Blender 2.78 on a Power Mac running El Capitan, 10.11.4.
