enumerate tag using the alphabet instead of numbers [duplicate]

Question

The default behaviour for the \begin{enumerate}tag is to sequentially list the items given by \item over the numbers {1, 2, 3, 4, ...}.

1. Is it possible to change this to the alphabet {a, b, c, d, ...}
2. How about Roman Numerals {i, ii, iii, iv, v, vi, ... }
3. How is this done?

Note that I use emacs 24.3. Thanks for all the help.

Answer 1

If you use the enumitem package, you can easily change the style of the counters.

Here is an example using small letters, capital letters, and Roman numbers as counters:

\documentclass{article}
\usepackage{enumitem}
\begin{document}

\begin{enumerate}[label=(\alph*)]
\item an apple
\item a banana
\item a carrot
\item a durian
\end{enumerate}

\begin{enumerate}[label=(\Alph*)]
\item an apple
\item a banana
\item a carrot
\item a durian
\end{enumerate}

\begin{enumerate}[label=(\roman*)]
\item an apple
\item a banana
\item a carrot
\item a durian
\end{enumerate}

\end{document}

Which results in:
