Vim
Vim, which stands for Vi IMproved, is a free multi-platform text editor. Vim's multi-mode full screen editing paradigm is a conceptual outgrowth of the original vi editor implementation that, since the early 1980s, has been distributed as an essential part of every operating system that is derived from Unix. Since its inception in the early 1990s Vim has grown to accommodate an extensive array of features, both original and derived from other free and commercial text editors. This success is an outgrowth of the development process which has been driven by the public publication of the Vim source code combined with the constant interaction between users, developers, and the original creator of Vim, Bram Moolenaar.
