Cyber_Angel, I think Jo, sonshine777 and I are talking area selection (which I always presumed to be the same as marquee selection). Depending what software you use you would either slick to define one corner and then click to define the opposite corner, or (my preference) you click for one corner, and keeping your finger on the mouse button drag till all the nodes you want to select are encompassed by the box you have dragged. let go of the button and they are selected.
