If you make much use of LaTeX's \footnote command, you may possibly have wondered if it's possible to use letters instead of numbers to indicate footnotes in the final document. For example, sometimes this is useful because it disambiguates between a footnote and a square (or cube, etc.) symbol. You can get LaTeX to use this convention by adding the line

\renewcommand{\thefootnote}{\alph{footnote}}

in your preamble (before \begin{document}).
