Imagine a track (or a section of a track) that is entirely populated by regions. You want to carry out an operation on the track, not one of the regions. So you … context-click on the track … but there’s a region in the way.
So we show you a menu that allows you to access both the region actions and the track actions.
That doesn’t work so well for things that more positional in nature (i.e. where you clicked matters in some way). That said, not much in that menu has that property.
