I usually run doxygen enabling graphs for includes (INCLUDE_GRAPH, INCLUDED_BY_GRAPH) and function calls (CALL_GRAPH, CALLER_GRAPH), and generate html docs. This way you get a "nice" clickable visualization, that helps you move around the code. Of course, you need also an editor, I'm not saying to just use doxygen. But for me at least it's very helpful.
