And here I would argue that, since the documentation is included with Emacs and can be pulled up in the editor, this is still a point towards its inherent discoverability. Again when you load emacs there's a link to the manual on its splash screen and as a guided tour. A lot of people rush to turn off this screen or suppress the menues on startup (which I get, the menu bar is pretty ugly) but they do have useful functionality for someone who doesn't know Emacs.
