Hello David, On my Mac, if I hold down the command key and click or drag with the mouse, it "plots" visible points on the graphic. These points are ALL copied to the clipboard so once I have created a bunch of ordered pairs by clicking or dragging , I can then paste them into a command line and put them into a list, etc. Hope that helps?
