# How to modify the symbol for items in an “itemize” environment (dots, not triangles)

\begin{itemize}
\item
\end{itemized}


I am getting

What I want is dots instead of triangles in an itemize environment.

\documentclass{beamer}
\useinnertheme{rounded}% _or_ as an alternative:
%\setbeamertemplate{itemize item}[ball]% see comment

\begin{document}
\begin{frame}
\begin{itemize}
\item Hello World!
\begin{itemize}
\item Hello inner World!
\begin{itemize}
\item Hello inner inner World!
\end{itemize}
\end{itemize}
\end{itemize}
\end{frame}
\end{document}


• This change also enumerate list, \setbeamertemplate{itemize item}[ball] only change itemize lists. – Fran Nov 22 '17 at 20:33
• Yes, but then everything else is not "rounded" – user2478 Nov 22 '17 at 20:36
• That's what I said :) – Fran Nov 22 '17 at 20:38
• that's right :-) – user2478 Nov 22 '17 at 20:50

I suggest you issue the instruction

\setbeamertemplate{itemize item}{\textbullet}


in the preamble.

Do please consult section 16.3.3, "Setting Beamer's Templates", of the user guide of the beamer package for more information.

A full MWE:

\documentclass{beamer}
\setbeamertemplate{itemize item}{\textbullet}

\begin{document}
\begin{frame}
\begin{itemize}
\item Hello World!
\end{itemize}
\end{frame}
\end{document}

• Remark: The code provided above modifies the symbol that's shown for level-1 items. For items in level-2 and level-3 itemized lists, use \setbeamertemplate{itemize subitem}{...} and \setbeamertemplate{itemize subsubitem}{...}, respectively. (Aside: Your audience will very much appreciate if your beamer document doesn't feature 3 nested itemized lists...) – Mico Nov 22 '17 at 6:55
