WYSIWYG
/wiz'ee-wig/ adj. Describes a user interface under
which "What You See Is What You Get", as opposed to one that uses
more-or-less obscure commands that do not result in immediate
visual feedback. True WYSIWYG in environments supporting multiple
fonts or graphics is a a rarely-attained ideal; there are variants
of this term to express real-world manifestations including
WYSIAWYG (What You See Is Almost What You Get) and
WYSIMOLWYG (What You See Is More or Less What You Get). All these
can be mildly derogatory, as they are often used to refer to
dumbed-down user-friendly interfaces targeted at
non-programmers; a hacker has no fear of obscure commands (compare
WYSIAYG). On the other hand, EMACS was one of the very first
WYSIWYG editors, replacing (actually, at first overlaying) the
extremely obscure, command-based TECO. See also WIMP environment.
[Oddly enough, WYSIWYG has already made it into the
OED, in lower case yet. --- ESR]
