I've been working in Avid 6.5 and haven't been able to find a menu for grouping and multi-grouping options. In the past, it's been in the upper right corner of the sequence monitor in source/record mode. It enables you to choose options like "Audio follow video" and what camera angle you want to choose. It's signified by the little group clip icon. I've looked all over including the command palette to find it with no luck. Is it located somewhere else in 6.5?
