Please allow me to explain my situation. I am using Beamer overlay for a quiz. (And I love the pdf output). So, I give the students multiple choices on first slide. And next slide they get the answer. But, I want to add an additional comment after the answer, to describe little more about the topic. Here is what I have.
\begin{frame}{Programming Basics}
\texttt{Comments are followed by \underline{\hspace{2cm}}}
\begin{enumerate}
\item<1> !
\item<1> @
\item<1> ::
\item<1-2> ;
\item<2> Only show this in second slide, ; I am comment
\end{enumerate}
\end{frame}
I like \setbeamercovered{transparent}
so I don’t want to set to invisible
. I just want the last item to show up after the answer, without a grey transparent item showing up on first slide, because this can give them a hint!!! (See the attached image)
I did some research but could not find the answer. Thank you.
