I can't understand this :
How it works: This script operates on the active window. Hold down the configured modifier key (default: xbutton1, the "back" button on many mice) and click the left mouse button. While still holding both the left mouse button and the modifier down, move your mouse anywhere, and let go of the left mouse button, then the modifier. The point at which you clicked the left mouse button is the new top left coordinate of the active window, and the point you let go of the button is the new bottom right coordinate (or the other way around, depending on which way you moved the mouse relative to the window's previous coordinates). In short- you both resize and move the window in one swift action. Trace windows into empty spaces of your desktop! Have a lot of windows open across multiple monitors and you can't easily tell where the window you just alt tabbed to is? Trace it into view!"
