Description of Features
JOE includes an integrated help system and a reminder of how to get help is always on the screen. The key sequences in JOE are similar to those of WordStar and Turbo C: many are combinations of the Control key and another key, or combinations of Ctrl+K and another key, or combinations of the Escape key and another key. Numerous settings are also available through Ctrl+T. The program is generally customizable through an extensive configuration file, and it supports color syntax highlighting for numerous popular file formats, a feature that is also configurable.
JOE comes with macro files that emulate Emacs keybindings (when invoked as jmacs), Pico (when invoked as jpico), or WordStar (when invoked as jstar). There is also a variant called "rjoe", which is restricted in that it allows one to edit only the files specified on the command line (which can be useful to enforce the principle of least privilege).
While the user interface of the editor is reminiscent of DOS editors, it also includes the typical Unix editor features such as internal command history, tab completion in file selection menus, regular expression search system and the ability to filter (pipe) arbitrary blocks of text through any external command.

“A sound mind in a sound body, is a short, but full description of a happy state in this World: he that has these two, has little more to wish for; and he that wants either of them, will be little the better for anything else.”
—John Locke (1632–1704)
“The great object in life is Sensation—to feel that we exist, even though in pain; it is this “craving void” which drives us to gaming, to battle, to travel, to intemperate but keenly felt pursuits of every description whose principal attraction is the agitation inseparable from their accomplishment.”
—George Gordon Noel Byron (1788–1824)
“Art is the child of Nature; yes,
Her darling child, in whom we trace
The features of the mother’s face,
Her aspect and her attitude.”
—Henry Wadsworth Longfellow (1807–1882)
