About the Book

Emacs is the ultimate extensible editing environment. There's a reason it's been around for so long and is used by so many programmers.

Like with any flexible, powerful tool, learning Emacs is a major investment. Emacs Mastery will help by covering basic, intermediate, and advanced topics that will improve your effectiveness and by showing you some things Emacs can do that you might not know about. Tetris, anyone?

This book is a personal meandering through Emacs. It's a collection of tips and hints I've collected over decades of using Emacs, organized and expanded into a useful compendium of ideas for you to try and make your own.

Emacs Mastery is not a tutorial, though it does cover some basic things because I've found even some experienced Emacs users don't always remember some of the simpler, easier ways to do things like navigate on the page.
