Also check out: Emacs eww. Handy when you are reading through a manual with lots of code examples, and copy pasting from a web page becomes work by itself.

Just in case you're put off by the thought of Emacs keychords, note that you can also use mouse to move backward and forward through history (it has icons for those), and of course you can click links.

But more importantly, it's Emacs. So if you wanted, you can press a key have the code copy-pasted to a temp file, run the compiler on that, display the result in a new window and file away both the code and the result to an org file for further studying.
