I am new to SM so forgive me if this is a newbie question....Is it possible to make keyboard assignments to increase/decrease layer audio volume?

Thanks Rick, I had checked the Mouse and Keyboard settings.  The only thing I could find was 'fade' controls which transition the audio/video on and off, but I didn't see anything that allowed finer control of audio level.

Any other info would be appreciated.

If this is not presently supported...it would be a good feature request.
