Setting edges in proof environment

Question

I would need to move the itemize environment used in the proof environment more to the left side of every slide. I used \setbeamersize{text margin left=15pt,text margin right=20pt} for moving the definition and theorem environments but what can I use for itemize items in the proof environment?

Answer 1

Change leftmargini:

\documentclass{beamer}
\usetheme{Boadilla}

\begin{document}

\begin{frame}

\begin{proof}
\setlength\leftmargini{10pt}
\begin{itemize}
\item First item.
\item Second item.
\item Third item.
\end{itemize}
\end{proof}

\end{frame}

\end{document}
