I'm trying to tell the difference between when a user hits the ENTER key to exit an MCM menu dialogue and when they hit the TAB key to cancel out of it. (The problem for me is that OnOptionMenuAccept seems to get triggered either way)

I was thinking I'd register for controls to differentiate this, and I think tab is the "Tween Menu" control, right? But I can't seem to figure out, what control would the ENTER button be? Is it possible to register for that button as a control too?
