JED is a highly customizable text editor offering most of the commonly used features of EMACS without the proportions of EMACS. The default configuration uses EMACS keystrokes, though WordStar keystrokes are available, and most any keystrokes can be programmed.n JED is customizable and programmable in the language S-Lang, which can look like Forth or C, depending on your preferences.
