Vim is a highly configurable text editor used for efficient text editing and programming. It is known for its modal interface, which allows users to switch between different modes for inserting text, navigating, and executing commands. This design helps users perform tasks quickly without relying heavily on a mouse. Originally created by Bram Moolenaar in 1991, Vim is built on the foundation of the Vi editor, which was developed in the 1970s. It is available on various platforms, including Windows, macOS, and Linux, making it a versatile tool for developers and writers alike.
