This answer is going to be rather unortodox and might get downvoted but this is how I do it: I just skim throught all the sources, then somehow I am able to point approximate file and line of code where a specific question might be answered. This might sound "out there" but I realized during college I had the ability to recall the approximate location of specific information I needed from a textbox If I just skimmed through the whole book at the start of the semester. For years I did this out of intuition, then about 10 years ago I took a course named "photoreading" and to my surprise they were teaching my "ability" but with clear steps so anybody could use it effectively.
