Right, I picked that up when I first started working on this project. But it seems the guys at OUYA have altered (or maybe added) how the HOME category works. It seems to me, based on how the new update is working, that double tapping the (u) key invokes a different intent category than android.intent.category.HOME and that's what I'm trying to figure out; what is this new intent category? And is there a new intent action for it (as in not android.intent.action.MAIN)?

I guess to sorta draw out what I'm talking about,
Long pressing the (u) button:
Calls an intent with action android.intent.action.MAIN and category android.intent.category.HOME. This will launch what ever Launcher is set as default home launcher (by default the Ouya Launcher)
(this I'm aware of and don't care about this since I can't override the Ouya System Menu with this)

Double pressing the (u) button:
Calls an intent with an unknown action (might be android.intent.action.MAIN) and an unknown category. This will launch the OUYA System Menu (not the Ouya Launcher) where you can resume your current app or exit to the Ouya Launcher.
(^ This is the intent that I'm trying to understand and figure out)
