beamerfonts
When using beamer with the warsaw theme, how can one set the text on all frames to appear in boldface?
Here is an MWE, I want text on both the slides to be in boldface.
\documentclass[11pt]{beamer}
\usetheme{Warsaw}
\usepackage[utf8]{inputenc}
\usepackage[english]{babel}
\usepackage{color,soul}
\author{author}
\title{title}
\institute{institute}
\begin{document}
\begin{frame}
\frametitle{Outline}
text on this slide
\end{frame}
\begin{frame}
test one this slide
\end{frame}
\end{document}
the initial solution I proposed (it's on the bottom now) was theme-dependent since it involved a redefinition of the footline template (which may vary from them to theme). Here now I present a simpler solution which doesn't depend on the theme used. The idea is to use the background canvas template and a \node (inside a tikzpicture environment with the remember picture,overlay options) to place the button at the desired location:
\documentclass{beamer}
\usepackage[utf8]{inputenc}
\usepackage{tikz}
\usepackage[brazil]{babel}
\usetheme{Boadilla}
\newcommand\AddButton{%
\setbeamertemplate{background canvas}{%
\begin{tikzpicture}[remember picture,overlay]
\node[anchor=west] at ([yshift=20pt,xshift=1em]current page.south west)
{\hyperlink{toc}{\beamergotobutton{Voltar ao início}}};
\end{tikzpicture}%
}%
}
\title{Apresentação RLZ}
\author{RLZ}
\date{\today}
\begin{document}
\begin{frame}
\titlepage
\end{frame}
\begin{frame}[label=toc]
\tableofcontents
\end{frame}
\AddButton
\section{Test Section}
\begin{frame} test frame \thepage \end{frame}
\begin{frame} test frame \thepage \end{frame}
\begin{frame} test frame \thepage \end{frame}
\end{document}
Here's one possibility; the idea is to define a command (\AddButton in my code) that oncludes the button as a part of the footline template used by the Boadilla theme; simply issue the command at the point where the button must be included in all successive frames (you can change the position of the button by changing the lengths used in the lines marked % HERE in my code):
\documentclass{beamer}
\usepackage[utf8]{inputenc}
\usepackage[brazil]{babel}
\usetheme{Boadilla}
\makeatletter
\newcommand\AddButton{%
\setbeamertemplate{footline}
{
\leavevmode%
\vskip-15pt% HERE
\hskip1em\hyperlink{toc}{\beamergotobutton{Voltar ao início}}% HERE
\vskip5pt% HERE
\hbox{%
\begin{beamercolorbox}[wd=.333333\paperwidth,ht=2.25ex,dp=1ex,center]{author in head/foot}%
\usebeamerfont{author in head/foot}\insertshortauthor\expandafter\beamer@ifempty\expandafter{\beamer@shortinstitute}{}{~~(\insertshortinstitute)}
\end{beamercolorbox}%
\begin{beamercolorbox}[wd=.333333\paperwidth,ht=2.25ex,dp=1ex,center]{title in head/foot}%
\usebeamerfont{title in head/foot}\insertshorttitle
\end{beamercolorbox}%
\begin{beamercolorbox}[wd=.333333\paperwidth,ht=2.25ex,dp=1ex,right]{date in head/foot}%
\usebeamerfont{date in head/foot}\insertshortdate{}\hspace*{2em}
\insertframenumber{} / \inserttotalframenumber\hspace*{2ex}
\end{beamercolorbox}}%
\vskip0pt%
}%
}
\makeatother

You can use the frametitle font and color; by default the text will be vertically centered, so you only have to add \centering to center the text horizontally:
\documentclass{beamer}
\begin{document}
\begin{frame}
\frametitle{Test frame}
\usebeamerfont{frametitle}\usebeamercolor[fg]{frametitle}
\centering
A line of text
\end{frame}
\end{document}
Best Answer
Just choose which elements of a frame you want to be bold.
\AtBeginDocument{\bfseries\selectfont}makes the normal text bold.More options can be found at https://tex.stackexchange.com/a/183053/36296
