How to select multiple fingers to restrict the movement

I want to select multiple fingers with the manipulation tool like in the slap n’ sass tutorial.

You can select multiple objects either via Blender’s Outliner, or via the Ragdoll Manipulator by first turning off Symmetry and holding Shift when selecting.

Thanks. And btw how do I make the dummy collide with diferent objects as well as the floor?

See this answer here: How do you add collision objects to the scene for the ragdoll to hit? - #2 by davidlatwe
