So, I want to map my F15 key to Hide the current application I'm in (Anyone know how to do this? I can't seem to figure out what 'exact command' to put into the dialogue box.), but every time I hit F15 it's launching Mission Control regardless of what I do. My Mission Control settings has it mapped to F4 (which also works), and I can't see a mapping for F15 anywhere in my System Preferences.
What gives?
