Thanks for the reply Darby. I'm working on a graphics kit of some broadcast deliverables. I try to keep the compositions extremely simple. There are any number of ways with nulls, splitting the layer, etc I could make this work, but I'm trying to allow the editor to have to adjust two position key frames on one layer. They set point A (say at 1 sec), then move to the second keyframe and set point B (at 2 sec) by adusting B, keyframe C (at 6sec) is automatically equivalant so the animation holds for those 4 secs. Its just one of those times I have marching orders to make this very simple for the editors.
