The features of GNU Emacs include:

• Content-sensitive editing modes, including syntax coloring, for a variety of file types including plain text, source code, and HTML.
• Complete built-in documentation, including a tutorial for new users.
• Full Unicode support for nearly all human languages and their scripts.
• Highly customizable, using Emacs Lisp code or a graphical interface.
• A large number of extensions that add other functionality, including a project planner, mail and news reader, debugger interface, calendar, and more. Many of these extensions are distributed with GNU Emacs; others are available separately.
