Emacs, the guided tour tour Intro intro
I’m reading the guided tour for Emacs, and it’s no fun. It’s like the biggest oversell I’ve ever seen. If this is a text editor, why do I know about the Tetris part before I understand what C-x C-s actually means? I know what it does, it saves, yays, but is it Ctrl-x and then Ctrl-s? Why does it say “type C-h t” if it means Ctrl-h followed by t? And what the hell is M-x, what key is M short for? I know the answer (and it’s not pretty) - the “type”ing you’re actually doing is issuing commands, if that makes sense. Somehow the text editor part doesn’t want you to enter any text, and all the buttons are different commands. This is to make it better to use, somehow. The fact that this guided tour hasn’t mentioned the command mode and input mode difference is just plain confusing for a first time visitor.
