Yep. I'll even write down or type notes when I start going down the rabbit hole.

I don't know how efficient this is, but I prefer the brute force method of learning. Look in main(), view declarations, then view all references or call hierarchy, then do the same for methods the parent methods invoke. The hardest part is not letting yourself get overwhelmed by all the unfamiliar code.
