Craig and Sharke - Thanks for the info but I guess I didn't explain myself well. I already know how to do both of those things.
I have a region selected and looping. I want to now export that exact section. Sure, I can get pretty close by dragging to select the region as Craig mentioned but I thought that there might be a shortcut to use that already defined region as the "selection" for exporting.
I did find a way to do it, though not a shortcut: on the control bar is a module for "Selection". I manually entered the " Select from" and "Select thru" to match the loop points. That does what I want.
