1. The document discusses using Vim in Android Studio and customizing the IdeaVim plugin. It provides an overview of Vim and IdeaVim, demonstrates basic Vim shortcuts and navigation, and shows how to define key mappings in the .ideavimrc file to execute common Android Studio actions in Vim. 2. The document also explores extending IdeaVim by creating custom EX commands and command handlers to execute system commands like adb from within Vim. 3. The author concludes they enjoyed customizing their setup, learned about the pairing programming approach when extending IdeaVim, and discusses Vim's learning curve.

What is Vim?
Vim is a highly configurable text editor
built to enable efficient text editing. It is
an improved version of the vi editor
distributed with most UNIX systems.
Vim is often called a "programmer's editor,"
and so useful for programming that many
consider it an entire IDE. Vim is perfect for
all kinds of text editing, from composing
email to editing configuration files.
– Johnny Appleseed
