Drag & drop support (e.g. to interactively move a window)

[dumblob]

I wonder if there is any drag & drop support for window management. Ideally in conjunction with keyboard (e.g. I need to press & hold Shift on a keyboard and then I can use LMB to start drag & drop while in the mean time I can release Shift and then finish the drag & drop action).

Do you think this would be possible?

Thanks!
