Learn Enough Text Editor to Be Dangerous is designed to help you learn to use what is arguably the most important item in the aspiring computer magician’s bag of tricks: a text editor. Learning how to use a text editor is an essential component of technical sophistication.
Quite bad. Since this is the next book after Learn Enough Command Line To Be Dangerous, you can substitute the first chapter (about Vim) with vimtutor (just type in bash vimtutor) which is a better and more practical introduction to Vim. Chapter 2 and 3 are macOS oriented, though some commands "Command + ..." work with other systems via "CTRL + ..." it is not specified in the book. It looks to me like a filler for the trio Learn Enough - Developer Fundamentals. I think most people have used a text processor in their life and the difference between text processor and text editor as well as the few tips on advanced editing could be presented in a blog post. More on chapter 2 which presents auto-completion via tab use which I strongly disagree for someone who is starting their tech journey. So i would enforce the idea of typing yourself all the code even when coping it from a book or the web, unless you are working on a project at your job where time is sensitive. When you are learning, typing everything in yourself, i find it to be quite beneficial.
