How to copy more than 1 frame at the time?
Go to your layers, click one frame to select it, click and drag to select more than 1. right click>copy frames.
What does ctrl + shift + Fn8 do?
Creates a new symbol, might be a graphic, movieclip or button. In your case, you need either a graphic or a movieclip.
Paste the frames?
go to your layers and right click where you see a single blank frame > paste frames.
If you're exporting it as a .gif the loop wont show. You cant make an animated .gif using movieclips, not in flash at least.
