windowOrder ?-w <win>? (-above|-below) otherwin
Reposition the window win (or the frontmost window if -w is not specified) relative to otherwin.
With the -above option, the window is ordered immediately in front of otherwin. If otherwin was the current window, then win becomes current window.
With the -below option, the window is ordered immediately behind otherwin. If win was the current window, then the document window that was in second position (whichever it is, not necessarily otherwin) becomes the current window.
