Quickly Preview High Playback Quality frames in Multiclip

Here's a quickie.

When you're editing a multiclip sequence and have RT set to Low or something other than High and you want to check the focus of a shot or something that requires seeing it at High Quality, simply tap Control + Z to toggle Excess Luma on and off. When it's on -and you see the green check mark or yellow exclamation point- you'll be viewing that frame in High quality.

Unfortunately, it won't stay high quality for playback if you have RT set to something like Low Quality playback.
