Changing the font for “alert” in beamer

Question

I would like to change the behaviour of \alert so that the text is still red but now boldfaced, say. How can I do this? I have Googled, but all I can find is how to change the colour, as in Changing style of alert environment in beamer.

Answer 1

After some digging, I located the definition of \alert in beamerbaselocalstructure.sty. The rest was easy. ;-)

EDIT: There's also a more "beamer-like" way. :-)

\documentclass{beamer}

% \renewcommand<>{\alert}[1]{\begin{alertenv}\bfseries#2#1\end{alertenv}}
\setbeamerfont{alerted text}{series=\bfseries}

\begin{document}

\begin{frame}
\alert{Some text.}
\end{frame}

\end{document}
