[Not sure if this is Mutter-related or GNOME Shell-related thing. Please move it if I've posted it to the wrong place. Thank you!]

I've discovered some really useful keyboard shortcuts recently in Windows 7 (maybe they're also available on Vista, I don't know) and I think it'd make sense to implemented them in GNOME 3, since both desktops share this drag-windows-to-specific-areas-to-resize feature (the behavior I'm referring to is demonstrated in this video: http://www.youtube.com/watch?v=Ip9Bgjaspjs).

These shortcuts are the following:

Windows key + Up  = Maximize window
Windows key + Down = Minimize window (maybe this one wouldn't make much sense in GNOME 3, since minimize buttons are gone)
Windows key + Left = Move window to the left and resize it so it fits half the screen
Windows key + Right = Move window to the right and resize it so it fits half the screen

Sure these shortcuts aren't obvious and the average user probably won't use them, but I think power users will find them pretty convenient (at least I do). I also believe the design team plans to release a brief, brochure-like user guide for new GNOME 3 users, including some basics shortcuts. Maybe these ones could be included there to increase its discoverability (in fact, I discovered them by accident in Windows 7).
