NEdit

NEdit, the Nirvana editor, is a text editor and source code editor for the X Window System. It has an interface similar to text editors on Microsoft Windows and Macintosh, rather than to older UNIX editors like Emacs. It was initially developed by Mark Edel for Fermilab and released under a restrictive licence, but later relicenced under the GPL-2.0-or-later (plus Motif clause) and became an independent open-source project maintained by a team of developers. Nedit was also distributed with the IRIX operating system.
