Duplicate a video

Hi all,

Is it possible to create a video, then duplicate it so you can have two different edits? For example I've got a video with some overlays that I like, but perhaps i want to shorten the video, change the overlays, or transition effects. I don't want to loose the original version in case I don't like what I end up with. I was hoping there was a simple right-click option to duplicate a video, but I couldn't find one.

Thanks,
Brett
