Insertion Marker
	A green marker defines a placement point for adding geometry and objects. To move the green marker in any view, press and hold the X key while moving the mouse. When you add an object it is placed at the origin of the green marker. When you add new brush points, the top polygon is placed at the same height as the origin of the green marker.
