No "Select" button ?

[osn19]

I was playing Batman Arkham City on Onlive, and everything works really great.

Except I need to push the "Select" button to open the map in the game.

How can I do that on the Shield Portable, as all the buttons are there except this one ??

Thanks !

@osn19 - it's there.
