I have a dozen objects in my scene right now. I have one of them moving along the Z axis. I want to copy that movement to the other objects. Right now I'm being told I should use CTRL+L to link animation data from the one object to the rest. However, I later want to be able to manipulate the individual objects further, but when I do that, it copies that change to all of the objects, because their animation data is linked. How can I copy the keyframes from one object to many others without using the Link Animation Data command so that I can manipulate them individually after that?
