Jumpstart using the VIM editor productively in just a few minutes. VIM is for everyone, not just for nerds!
There seems to be a notion among uninformed beginners in programming that the VIM editor was born out of some sort of a relic and is used only by nerds who are fond of Unix. It is true to some extent. But relics are also classics that have a charm of their own which cannot be replicated. It is a privilege to learn them.

This book is an excellent guide on how to use the UNIX Vim editor. It begins by guiding you on how to use the extended text objects and powerful regular expressions in the Vim editor. In most cases, people would like to open multiple files simultaneously.
