LaTeX is the reason why LyX differs from other word processors.
|
||||
LyX is a graphical user interface (GUI) frontend for LaTeX.
|
||||
It is designed to typeset documents using LaTeX without knowing its macro
|
||||
commands.
|
||||
But although LyX can never support all commands graphically, it offers
|
||||
its usage, so that LyX is as functional as LaTeX.

LaTeX makes LyX different from other word processors.

LyX is a graphical user interface (GUI) frontend for LaTeX, designed to

typeset documents without knowing LaTeX's macro commands.
|

LyX does not provide graphical support for all the countless existing LaTeX

macros, but can parse all of them.
