JED is a freely available text editor for Unix, VMS, MSDOS, OS/2, BeOS, QNX, and win9X/NT platforms. Although it is a powerful editor designed for use by programmers, its drop-down menu facility make it one of the friendliest text editors around. Hence it is ideal for composing simple email messages as well as editing complex programs in a variety of computer languages.
Jed is just another text editor. You may like it, you may not. Compare Emacs, Vim, etc.
