Adding a Vertex

To add a vertex to a polygon, first select the polygon by clicking inside the zone or by dragging a box around it. Hold the Ctrl key, and move the mouse close to the side where you want the new vertex to be added. Once the side is highlighted, click with the mouse. A new vertex will be added between the two vertices that the highlighted side connected. You will not always be able to add the vertex in the exact place you want, so you may have to move the new vertex to the place you want it to be.
