I set a new origin in the Crosshairs tool. How do I return it to the default setting?

The default origin for the Crosshairs tool is either in the upper lefthand corner of your screen or in the lower lefthand corner of your screen, depending on which you have set in xScope's preferences. To return to this default after changing the origin, simply move your cursor to either origin position on your screen and press cmd-0, setting a new crosshair origin in the desired default location.
