It may well be that everyone already knows this but just in case: the readme file explains that they left this information out of the documentation, and since no-one here has mentioned it I thought I would.
If you hit F5 AS7 (I have Pro, I don't know about Debut) does a quick animated render and pulls up Itunes to show it. I haven't found any way to set any parameters for this but the animations seem to look okay.
The other versions do that too, its like when you export normally but without effects and i think the resolution is the half of the one you have set in project settings.
When i press f5 on my computer the video opens with Quick time.
I use F5 a lot as a way to check my progress, but find that there are certain effects that do not appear using F5... they will only show up in a true Render.
