How can I change the font size for the entities on a pathway?

By default the font size for the entities on a pathway is set in order that the text fit the smallest entity. To change the font size for the all the entities at one time on a pathway: 

1.  Select Advanced Scaling from the drop down menu in the far upper right (to the right of the “Fit All Entities to Window” button).
2.  In the Advanced Graph Scaling window, select the “Scale Entities Label” radio button.
3.  Move the scroll bar to the left or right to reduce or increase the size of the labels.
