I can't claim that this is as simple as your technique, but you could also
open the files in FreeRIDE. The navigation pane gives you the same info in a
collapsible tree, plus if you click on any entry (module, class, or method),
the edit pane is scrolled to that spot in the code and displayed with full
syntax highlighting.
