How do I see what's in a #Include

In an effort to learn more about what's going on inside and get a better understanding of the interface(s), I'd like to see the contents of certain libraries.

For example, even something simple like the <LiquidCrystal.h> header and .cpp code.

I've tried opening the files in Notepad, but the result is unformatted and difficult to read. I thought there would be something in the IDE, but haven't found it. I know there has to be a better way.

Thanks,

Use Notepad++, then. Much better than the POS from Microslop.

Notepad is not a text editor, its the weapon of last resort. On Windows machines
use Wordpad, it at least recognises newlines!

Its time to take the plunge and find a proper text editor (ie for programmers) to
use. Everyone has their favorite, I'm sure wikipedia has a summary of the main
options. The Arduino environment's editor is a pale shadow of a real editor.

Let's not turn this thread into a religious war on which editor is best. Just agree
that notepad is worst!

[ Ah yes, here it is Source-code editor - Wikipedia ]

Notepad++ is very good for looking at code.

Don't confuse it with Notepad that MS supplies with Windows. That is awful for looking at code.
