in iOS mavericks, each display (ie monitor) has it's own space.. now there are many advantages to that. But then there are also advantages to the old way of doing it (ie i want both my monitors in say [view 1] to be for my Xcode app.. the 2nd two for my chrome etc)..

now preferences offers you the option of going either the old way or new way via the `Display have separate spaces` option: ![enter image description here][1]


however I want the best of both worlds: I want each screen to have its own space.. but then I also want a keyboard shorcut where I can move **both screens** at the same time. How is that possible?
