OS X Mountain Lion: keyboard shortcut to move current window to another space In OS X Mountain Lion, is there a way I can assign a keyboard shortcut to move the active window to a specified space (or even the adjacent space if an arbitrary space can't be specified).

Ideally, the space to which the window is moved to, won't itself get activated in the process. That is, the window will simply disappear from the current space, while the current space won't itself change.

I am open to all options: AppleScript, objective C, tweaking with preferences etc.

Lack of this feature really gets in the way of the window management workflow!
You could use sizeUp.

sizeUp allows you to send the window to the next/previous space but also it has keyboard shortcuts for mounting a screen to the left or the right of a screen and sending it to the next/previous monitor.
