Change normalize to shift+level

I find a lot of times when I’m in loop/slice editor and quickly want to go to level mode and tweak the level button takes you to the normalize feature. Would be great if the normalize function could be shift+level in loop/slice editor instead since that is more of a function you go to for a specific task and don’t use as much as you switch between modes.

Just a small little tweak that would make the workflow a little smoother :slight_smile:
