-# The TeX document preparation environment
-''[Why TeX is not WYSIWYG](FAQ-notWYSIWYG.md)''
-outlines the reasons (or excuses) for the huge disparity of user
-interface between ''typical'' TeX environments and commercial word
-processors.
-Nowadays, at last, there is a range of tools available that try either
-to bridge or to close the gap.  One range modestly focuses on
-providing the user with a legible source document. The low end of the
-prettifying range is occupied by syntax highlighting: marking TeX
-tokens, comments and other stuff with special colors.
-Many free editors can cater for TeX in this way. At the other
-extreme we have [TeXmacs](http://www.texmacs.org),
-a&nbsp;document processor using
-TeX's algorithms and fonts for both editor display and printing.
-TeXmacs does not use the TeX
-language itself (though among other formats, LaTeX may be exported
-and imported).  A bit closer to LaTeX is
-[LyX](http://www.lyx.org/), which has its own
-editor display and file formats as well, but does its print output by
-exporting to LaTeX.  The editor display merely resembles the
-printed output, but you have the possibility of entering arbitrary
-LaTeX code.  If you use constructs that LyX does not
-understand, it will just display them as source text marked red, but
-will properly export them.
-Since a lot of work is needed to create an editor from scratch that actually is
-good at editing (as well as catering for TeX), it is perhaps no accident that
-several approaches have been implemented using the extensible Emacs editor.
-There are though a very large number of (La)TeX-specific editors: see
-<https://tex.stackexchange.com/q/339/> for a (non-comprehensive) list.
-A different type of tool focuses on making update and access to previews of the
-typeset document more immediate. This is typically handled using a system
-called SyncTeX, which allows the relationship between lines in input and
-position in PDF output to be tracked. Thus it is possible to switch directly
-from a (potentially long) source to the resulting output, or _vice versa_. A
-very large number of the editors mentioned above support this technology.
-The different approaches offer various choices differing in the
-immediacy of their response, the screen area they work on (source or
-separate window), degree of correspondence of the display to the final
-output, and the balance they strike between visual aid and visual
-distraction.
