This is one of the things that makes Emacs one of the coolest pieces of software to me. 98% of the operations it can do, are defined in functions, which you can search for easily in the M-x pane with something like Helm, and boom. Even navigation. It's a near fully self-documenting editor that I rarely need to look up help on. Never forget how to activate an action again. Remember what the action is, type it, find the matching command that is aptly-named, push enter to run it. And, with Helm for example, it even shows the keybind next to it.
