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.

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. :-)


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


\alert{Some text.}

  • By the way, the former \renewcommand didn't work for me for some reason... the latter does though!
