Vim Overview
Vim is a free, open-source text editor for Windows, macOS, and Linux, created by Bram Moolenaar as an improved version of the classic Unix vi editor. It is a modal editor: keystrokes mean different things depending on whether you are in normal, insert, or visual mode, which lets experienced users edit text at high speed with the keyboard alone, rarely reaching for a mouse. Vim is prized for being fast, lightweight, and available almost everywhere, from full desktops to remote servers over SSH. It offers powerful features such as multi-level undo, syntax highlighting for hundreds of languages, search and replace with regular expressions, macros, split windows and tabs, and an enormous ecosystem of plugins and configuration through its scripting language. A built-in tutorial helps newcomers climb the initial learning curve. The official download is provided by the Vim project.
