How can I see ALL of the source including library code

I have a somewhat complex project that came from an "example". I'm using the regular Arduino IDE. There are numerous .h and .cpp library modules that get included, but they come from various libraries.

Is there a way to get the compiler/IDE to show me the code for the INCLUDE'd modules? Much like it does with tabs when I place a .h or .cpp modules in the same directory as the .ino module?

Thanks, Ira

That's what I was afraid of - it's kind of a cascading problem. Thanks

Check out Eclipse / Sloeber. Since starting to use it, I can't see myself doing serious software development in the Arduino IDE ever again.
