Save As:
Allows you to choose a new file name and location for your scene(folder).

New Version:
When a scene has several versions, the drawings and palettes are the same between all the different scene versions. You can modify the timing, effects, parameters and camera motions in a specific scene version, but if you make change to a drawing or a palette, the change will affect all scene versions.
