there are some new standard Win+key shortcuts for use inside apps (Win+Z brings up the toolbar that appears when you swipe the top/bottom edge and Win+I brings up the settings bar that appears if when you swipe the right edge, though these can also be invoked by hovering the mouse to the right edge of the screen or right clicking).
After 2 decades, Microsoft finally realises that combining the CTRL and META keys was a horrible idea? Now if only Linux distros would realise this too...
And not break shortcuts either... (I'm still trying to figure out why Alt+Tab broke when I installed Ubuntu 12.04, the shortcut is in fact assigned, for the record)
