 that details Vim's features. This manual can be read from within Vim, or found online.

Vim also has a built-in help facility (using the :help command) that allows users to query and navigate through commands and features.

Customization


Part of Vim's power is that it can be extensively customized. The basic interface can be controlled by the many options available, and the user can define personalized key mappings—often called macros—or abbreviations to automate sequences of keystrokes, or even call internal or user defined functions.

There are many plugins available that will extend or add new functionality to Vim. These complex scripts are usually written in Vim's internal scripting language vimscript
