Once you have drawn a path diagram, or drawn it partially at least, you can use one additional method of choosing further operations on the path diagram. You can move the mouse pointer over any object in the path diagram (that is, any rectangle, ellipse, arrow or caption), and click the second mouse button. Then Amos will display a menu of operations that can be performed on that object. For example, using the second mouse button to click on an ellipse pops up a menu of things that you can do to ellipses.
