Line spacing for all enumerate / itemize blocks (beamer)

Question

I just wonder, how it is possible to increase the spacing between between each bullet-item (item line) using beamer?

Is it possible to adjust the line spacing with defbeamertemplate or setbeamertemplate?

Thank you so much!

Answer 1

I believe \itemsep is reset at the start of each itemize or enumerate and is given different values for different levels or when cramped. For a global value, see Global setting of spacing between items in itemize environment for beamer

\documentclass{beamer}
\begin{document}
\begin{frame}
\begin{itemize}
\item Here I go again
\item creating a MWE\itemsep=2em
\item for a first timer.
\end{itemize}
\end{frame}
\end{document}
