Hi.
I assume you want to move multiple objects, layers, tween, and so on.
One approach is:
- Select the layers you want;
- Right-click them and choose Copy Layers;
- Press Ctrl/Cmd + F8 to create a new symbol;
- Choose Graphic (or Movie Clip) and hit OK;
- Inside of this new symbol, right-click and select Paste Layers;
- Go to the Library panel and drag and drop a instance of this newly created symbol to the stage;
- Create two key frames;
- Position your object in opposite sides of the screen;
- Right-click between them and create a Classic or Motion Tween.
I hope this all make sense.
Please tell us if this is what you want.
Regards,
JC
