<td><font face="Times New Roman, Times, Serif" size="2">Emacs originally
was an acronym for Editor MACroS. RMS [Richard M. Stallman., founder of
the Free Software Foundation] says he ''picked the name Emacs because
'E' was not in use as an abbreviation on ITS at the time." The first
Emacs was a set of macros written in 1976 at MIT by RMS for the editor
TECO (Text Editor and COrrector, originally Tape Editor and COrrector)
under ITS on a PDP-10. RMS had already extended TECO with a real-time
full screen mode with reprogrammable keys. Emacs was started by Guy
Steele as a project to unify the many divergent TECO command sets and
key bindings at MIT, and completed by RMS.</font></td>

mythology, however, Emacs has come to stand for escape-meta-altcontrol-shift,

to suit my style of work. I actually prefer it to vi, but now that I
must work on Windows machines as well as UNIX and Linux ones, I find
that to use my custom keybindings, I need to invest substantial sums in
