Epoch is GNU Emacs on steroids: an adaptation of GNU Emacs with lots of additional support for features made possible by the X11 windowing system. These features include multiple editing windows, arbitrary colors and fonts (fixed-width and proportional), selectable zones per buffer with arbitrary display styles (font, color, underline, stipple, pixmap), an optional separate minibuffer window, improved keyboard and mouse handling, full 8-bit character set support, and more.
