Emacs Tutorial
In my Emacs video tutorial I’ll cover installation on Windows and MacOS. Then we’ll cover what you’d learn in a standard 300 page book. We’ll cover how to move around, editing, repeating commands, regions, searching, buffers, frames, shells, macros and then I’ll cover how to setup a programming environment using Clojure as an example.
A cheat sheet follows the video below. Give it a try and you’ll learn Emacs in no time.
