In addition to all the excellent suggestions here, I will also suggest reading the free book "A Byte of Vim" (http://www.swaroopch.com/notes/Vim_en:Table_of_Contents http://www.swaroopch.com/notes/Vim_en:Table_of_Contents). This is how the book introduces itself: "A Byte of Vim" is a book which aims to help you to learn how to use the Vim editor (version 7), even if all you know is how to use the computer keyboard. The first part of this book is meant for new users who want to understand what Vim is and learn how to use it. The second part of this book is for people who already know how to use Vim and want to learn about features that make Vim so powerful, such as windows and tabs, personal information management, making it a programmer's editor, how to extend Vim with your own plugins, and more.
