The ever-popular Emacs, at least popular enough to be used by 4.5% of the respondents from the Stack Overflow survey of 2019. It is one of the usual symbol of extensibility and Free software due to its ecosystem of plugins and extensions integrating Emacs. It also allows the user to customize anything within it.

To show how extensible it is, here is a list of extensions that may as well be an entirely new application altogether:

- Entirely new spaced repetition on top of Org mode.

- Implementation of Roam Research with Org mode documents.

- Comprehensive Git client.

- Window managers inside Emacs.

Among other things, it is also where Org mode documents are often written from as well as making use of Org mode: Babel as a component for Reproducible research.

People have been building it with complex workflows all in one environment. In a way, Emacs is an entire operating system by itself.

As a complex text editor, you can start with Using the built-in help system of Emacs.
