A fast, compact Motif/X11 plain text editor, for most popular Unix systems. Features significant support for programmers including syntax highlighting, macro language, and streamlined keyboard navigation. Mature and stable.
After all these years, NEdit is still the best editor.
I still use Nedit every day on Linux and OS X. It is a fantastic, light-weight but powerful editor. I am not alone. At our organization there are over a dozen other users. Now that OpenMotif builds in a much more stable fashion on these platforms, it has gotten even easier to install.
