Same-name Animations
You can create animations on multiple layers and multiple atoms that share the same name; those animations will always play and scrub together.
Animation sets
You can also set up an animation set in the sequence screen, this behaves similarly to same-name animations, except that you can have more than one animation of the same set in the same layer. Whenever one animation plays, all layers will switch to the first available animation of that set, if available, across atoms.
