Learn a very easy technique to link any keyframed animations to a slider. With the Linear Link Time Remap iExpression, this is very easy: Just keyframe the animation (using arbitrarily many properties), set the start and end frame of your keyframed animation in the iExpression parameters and apply it to all those properties. Now al those keyframes are controlled by the slider, i.e. if you move the slider from 0 to 100, the animation plays back exactly as you keyframed it.
