I was wondering whether someone could explain what the following preamble commands actually do. I am a complete novice.
\newcommand\suppress[1]{}
defines a new command named "\suppress" that does nothing (the braces are empty in the definition)
\newcommand\deleted[1]{\xout{#1}}
defines a command "\deleted" that strikes out text (needs the LaTeX-package "ulem")
(have a look at chapter 22.13.2 of
http://wiki.lyx.org/uploads/LyX/LyXMathebefehle/LyXMathebefehle.pdf (http://wiki.lyx.org/LyX/LyXMathebefehle)
to see how it works.
\newlength\wvtextpercent
define a new length named "\wvtextpercent"
\setlength\wvtextpercent{0.009\textwidth}
set the length to 0.009 times the length "\textwidth" For the definition of \textwidth, have a look at
http://wiki.lyx.org/FAQ/Units
(in LyX \textwidth is called "text%")
\newbox\strikebox
\def\strike#1{\setbox\strikebox \hbox{<#1>}\hbox{\raise0.5ex\hbox to 0pt{\vrule height 0.4pt width \wd\strikebox\hss}\copy\strikebox}}
defines a box that strikes out its content
\setlength\parindent{0pt}
\setlength{\parskip\}{\smallskipamount}
sets the paragraph skip to small. You don't need this, use the menu Layout->Document->Layout instead.
