# Setting icon in Beamer button

Let's say I have the following MWE (from here):

\documentclass{beamer}

\begin{document}
\begin{frame}

\end{frame}
\end{document}


It gives this:

Now, I want to change the left triangle icon (just before Home page) by another symbol (say, by \faHome from fontawesome package). How can I do that?

The default definition of these symbols can be found in beamerbasenavigation.sty. So for example if you want to modify the symbol for your home page, which uses the returnbutton:

\documentclass{beamer}

\usepackage{fontawesome}

\def\insertreturnsymbol{%
\faCoffee\space
}

\begin{document}
\begin{frame}
