General ⇒ Reduce row space

[xetal]

Code: Select all

\begin{topic}
\item[A] A
\item[B] B
\item[C] C
\end{topic}

How would I reduce the space?

Also, I am using \begin{document}. Is there a way of making the width of the document greater by overwriting just that property?

Thanks

For the first problem, you can use the paralist package and the compactenum environment (see the code below). For the second problem, you can use the geometry package to customize the layout of the page (I changed the textwidth in the code below). Read the documentation of the packages to see all the options they offer:

Code: Select all

\documentclass{article} 
\usepackage{paralist}
\usepackage[textwidth=15cm]{geometry}
\begin{document} 

\begin{compactenum}[A]
  \item A
  \item B
  \item C
\end{compactenum}

\end{document}

Addendum: of course, you can control the vertical separation between items in a standard list-like environmnet changing the value of \itemsep, as the following example shows:

Code: Select all

\documentclass{article} 

\begin{document} 

%-----with the standard separation between items
\begin{enumerate}
  \item[A] A
  \item[B] B
  \item[C] C
\end{enumerate}

%-----with less separation between items
\begin{enumerate}
  \setlength\itemsep{-4pt}
  \item[A] A
  \item[B] B
  \item[C] C
\end{enumerate}

\end{document}

Thank you! That was what I needed!
