Vim Editor

Vim (Vi IMproved) is a highly configurable, command-line-based text editor ubiquitous in the world of computer science and system administration. Its defining feature is its modal interface, which separates text insertion (Insert mode) from navigation and manipulation (Normal mode), enabling users to perform complex edits with efficient keyboard commands rather than relying on a mouse or menus. This design philosophy, while presenting a steep learning curve, allows for immense speed and power, making Vim a favored tool for programmers and system administrators who work extensively within a terminal environment to write code, edit configuration files, and automate text-based tasks.
