Chris,

Did you catch this in alt.sources?  I think that ``e'' is also known
as ``j''.

|> Other relevent features:
|>
|>     * Extremely small - the XENIX version is only 58K
|>
|>     * Help text can be left on while editing
|>
|>     * Key layout designed to eliminate headaches: ^Q and ^S are not used,
|>       both ^H and DEL are backspace.  Also, each user may customize
|>       his key layout by modifying a simple initialization file
|>
|>     * Versions for BSD, HPUX and XENIX 386 are included.  A simple tty
|>       driver is also provided to ease porting to other systems
|>
|>     * Currently only VT100/ANSI terminals are supported.  If the terminal
|>       has scrolling regions, J uses them.  Has well-tuned interruptable
|>       screen update algorithm
|>
|>     * Has: autoindent, word-wrap, overtype/insert, picture mode (right-
|>       arrow makes space past ends of lines), right margin (for paragraph
|>       formatting and center), and magic tabs (the column number of text
|>       after tab stops is preserved when inserting and deleting)
|>
|>     * The cursor column doesn't 'jump' when you move between long and
|>       short lines.  Instead the cursor column only jumps when you try to
|>       edit in an invalid place or if picture mode is set, the invalid
|>       place is made real by space filling
|>
|>     * Editor modes can be set depending on file extension
|>
|>     * No line length restrictions.  Binary files can be edited without
|>       difficulty
|>
|>     * Long lines are truncated, not wrapped (I.E., the screen scrolls to
|>       the right to get to the truncated parts)
|>
|> FIXES FOR THIS VERSION
|>
|>     * Shell escape lock-ups are fixed
|>
|>     * Paragraph reformat glitch is fixed
|>
|>     * Cursor update screwynesses fixed for picture mode
|>
|>     * Goto next word/Goto previous word/Delete word left and Delete word
|>       right were made more consistant
|>
|> NEW FEATURES FOR THIS VERSION
|>
|>     * ~ can be used at file name prompts to expand user home directories
|>
|>     * J now has undelete and redelete (you can go backwards and forewards
|>       through the delete buffer to select which text you want to undelete)
|>
|>     * J now has indent functions.  A marked block can be indented more
|>       or less. If you use an indent function outside a marked block, the
|>       lines with the same or greater indent level surrounding the cursor
|>       are marked
|>
|>     * Right margin was added for paragraph format and center line
|>
|>     * Goto matching parenthasis (or [ { ` < )
|>
|>     * ` was made the quote control character key because ^_ is not easy
|>       generate on many keyboard.  `` gets `
|>
|>     * tty drivers were rewritten.  This made the screen update faster
|>       (now the screen update is instantaneous on 20MHz 386s).  Screen
|>       update preempting also works better
|>
|> THE PLAN
|>
|>     Version 1.0.0 will be a complete rewrite.  It should be done sometime
|> before january.  These are my goals for it:
|>
|>     * Block oriented software virtual memory support (for less thrashing
|>       and elimination of file size limits caused by the system's process
|>       size limit)
|>
|>     * MS-DOS support
|>
|>     * X windows support
|>
|>     * Better integration with UNIX:  J will be able to process text
|>       through pipes (like vi), will have standard unix regular expressions,
|>       and will be usable as a 'more' program.
|>
|>     * Will be terminal independant and use termcap and terminfo
|>
|>     * Will have a ASCII/HEX dump display mode
|>
|>     * Will have complete program developement support (save&make, next
|>       error/previous error, tags file support)
|>
|>     * Will have a much more powerful scrolling algorithm.  I have a
|>       methode which is simpler and faster than even GNU-EMACS' Gosling
|>       algorithm
|>
|>     * All of this will require no changes to the basic keyboard layout-
|>       maybe one more added line of help text for new things
|>
|>     * It will probably have keyboard macros but it won't have much of
|>       an extension language.  Maybe in version 2.0.0
|>
|>     * I expect all of this not to add more than 30 or 40% to the size
