Sort by Number of References determines how the base set, or each group of references to it, is sorted in the view. If not chosen, then nodes are sorted alphabetically. Print Report to data.ctl outputs all visible reference information to a file called data.ctl in the current directory. This file provides a record of the visualization should you want to study it. A final option, Font Scaling , will make text grow and shrink just like other elements of the view when it's zoomed.
Text remains a constant size by default.
These options help you to navigate around the Execution View, by zooming and by varying the time dimension in the view. Home returns the view to the original scale and scroll position. Zooming can be done in several ways. One is to drag the mouse over a rectangular area to zoom in on. Another is to use the plus and minus keys to zoom in and out.
