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 designed for use both as a command-line interface and as a standalone application with a graphical user interface.

It is primarily used by programmers and system administrators for writing and editing code, configuration files, and other plain text documents. Vim is known for its modal editing approach, which distinguishes between insert mode for typing text and command mode for executing commands.
