# Beamer: Highlight current item in list

I'm using beamer for a presentation. There's an itemize environment on a slide. For this (and possible more) itemize, I want the following behaviour:

• highlight the item I'm talking about (e.g., bold)
• gray out the items I talked about already (e.g., by {\color{gray} old item}
• items I'm going to talk about later are not visible yet
• no code duplication (e.g., writing sentences twice)

What I startet with was

\begin{itemize}
\item<+> My first point
\item<+> My second point
\item<+> My third point
\item<+> And my last point
\end{itemize}


I tried to get this done by user-defined commands like

\newcommand{\grayout}[1]{
\item<+> #1
\item<+-> {\color{gray} #1}
}
\begin{itemize}
\grayout{My first item}
...
\end{itemize}


But this is not working well. How can I solve this issue?

• highlight the item I'm talking about (e.g., bold)

can be done by using \item<alert@+> or automatically with \begin{itemize}[<alert@+>]

• items I'm going to talk about later are not visible yet

\begin{itemize}[<+->]

• gray out the items I talked about already (e.g., by {\color{gray} old item}

This is more tricky. Normally this would need something like https://tex.stackexchange.com/a/288050/36296, but as your items are not visible before they are highlighted, you could simply change the colour to gray.

\documentclass{beamer}

\begin{document}

\begin{frame}

{
\setbeamercolor{itemize/enumerate body}{fg=gray}
\item My first point
\item My second point
\item My third point
\item And my last point
\end{itemize}
}
\end{frame}

\end{document}
