Canvas options and full screen playback

Hello, I'm looking for a way to change the canvas background to black. I can change the background of the video window to black, but what I'm trying to change is the area outside of the video. For example, if you go from the video fitting into your window to 50% and there is that gray area around your video....that's what I'm trying to change to black.

The other thing I would like to do is be able to show a video in Final Cut full screen so if a client comes into the office we can show it without showing the timeline and all the tools. There is a way to do it in Avid so I was thinking there should be a way to do it in here as well.

I know I can export it as a quicktime movie and play it full screen, but to save time and space I was hoping not to have to do that every time for proofing.

Thanks,
