The title says it all. It would be great to have shortcuts ( like R G B A in Nuke ) to view certain composite channels quickly. So you can do very precise color matching and A/B flipping between the full RGBA image and a single channel while you're working, without having to resort to using the Channels interface. Very very useful for color matching stuff.
It seems to me that the functionality is there, just not the shortcuts.
