Ctrl+Enter shortcut function gone?

Previously I use CS6 version. When I hit Ctrl+Enter, Bridge became compact or smaller, always on top of other windows, and it's very handy for me to drag items to other Adobe apps. I don't know what's this feature is exactly called. In Bridge CC version, the feature seems gone. The shortcut combination key is not working anymore. Browsing through the menus did not find it too. Perhaps I missed something? or simply it has been removed from this CC version?
