beamer add tag
Skyork (imported from SE)
I have some `beamer` slides with notes on the right hand side, and would like to horizontally and vertically center the text on the note page.

I've tried:

    \documentclass[11pt]{beamer}
    
    \usepackage[gen]{eurosym}
    \setbeamerfont{caption}{size=\scriptsize}
    
    \renewcommand*{\thefootnote}{\fnsymbol{footnote}}
    \renewcommand*\footnoterule{}
    \setbeamerfont{footnote}{size=\tiny}
    
    \setbeamersize{text margin left=7mm,text margin right=7mm}
    
    \usepackage{pgfpages}
    \setbeameroption{show notes on second screen=right}
    
    \begin{document}
    
    \begin{frame}{Slide Title}
    	Some text in the main slides
    \end{frame}
    
    \note{
    	\begin{center}
    		Center this horizontally and vertically
    	\end{center}
    }
    %------------------------------------------------
    
    \end{document}

Which results in:

I know we can use `\begin{frame}[c]` in the main slides but such option is not available for notes pages. Besides [this answer][2], is there a simple/straightforward approach?

The answer from @marmot beautifully explains how to centre individual notes. 

In case all notes should be centred, one could define a new template for the note page:

```
\documentclass[11pt]{beamer}

\usepackage[gen]{eurosym}
\setbeamerfont{caption}{size=\scriptsize}

\renewcommand*{\thefootnote}{\fnsymbol{footnote}}
\renewcommand*\footnoterule{}
\setbeamerfont{footnote}{size=\tiny}

\setbeamersize{text margin left=7mm,text margin right=7mm}

\usepackage{pgfpages}
\setbeameroption{show notes on second screen=right}

\makeatletter
\defbeamertemplate*{note page}{center}
{%
  {%
    \scriptsize
    \usebeamerfont{note title}\usebeamercolor[fg]{note title}%
    \ifbeamercolorempty[bg]{note title}{}{%
      \insertvrule{.25\paperheight}{note title.bg}%
      \vskip-.25\paperheight%
      \nointerlineskip%
    }%
    \vbox{
      \hfill\insertslideintonotes{0.25}\hskip-\Gm@rmargin\hskip0pt%
      \vskip-0.25\paperheight%
      \nointerlineskip
      \begin{pgfpicture}{0cm}{0cm}{0cm}{0cm}
        \begin{pgflowlevelscope}{\pgftransformrotate{90}}
          {\pgftransformshift{\pgfpoint{-2cm}{0.2cm}}%
          \pgftext[base,left]{\usebeamerfont{note date}\usebeamercolor[fg]{note date}\the\year-\ifnum\month<10\relax0\fi\the\month-\ifnum\day<10\relax0\fi\the\day}}
        \end{pgflowlevelscope}
      \end{pgfpicture}}
    \nointerlineskip
    \vbox to .25\paperheight{\vskip0.5em
      \hbox{\insertshorttitle[width=0.75\textwidth]}%
      \setbox\beamer@tempbox=\hbox{\insertsection}%
      \hbox{\ifdim\wd\beamer@tempbox>1pt{\hskip4pt\raise3pt\hbox{\vrule
            width0.4pt height7pt\vrule width 9pt
            height0.4pt}}\hskip1pt\hbox{\begin{minipage}[t]{0.71\textwidth}\def\breakhere{}\insertsection\end{minipage}}\fi%
      }%
      \setbox\beamer@tempbox=\hbox{\insertsubsection}%
      \hbox{\ifdim\wd\beamer@tempbox>1pt{\hskip17.4pt\raise3pt\hbox{\vrule
            width0.4pt height7pt\vrule width 9pt
            height0.4pt}}\hskip1pt\hbox{\begin{minipage}[t]{0.71\textwidth}\def\breakhere{}\insertsubsection\end{minipage}}\fi%
      }%
      \setbox\beamer@tempbox=\hbox{\insertshortframetitle}%
      \hbox{\ifdim\wd\beamer@tempbox>1pt{\hskip30.8pt\raise3pt\hbox{\vrule
            width0.4pt height7pt\vrule width 9pt
            height0.4pt}}\hskip1pt\hbox{\insertshortframetitle[width=0.67\textwidth]}\fi%
      }%
      \vfil}%
  }%
  \ifbeamercolorempty[bg]{note page}{}{%
    \nointerlineskip%
    \insertvrule{.75\paperheight}{note page.bg}%
    \vskip-.75\paperheight%
  }%
  \vskip.25em
  \nointerlineskip
  \begin{minipage}[c][.7\paperheight][c]{\linewidth}
    \centering
    \insertnote
  \end{minipage}
}
\makeatother



\begin{document}

\begin{frame}{Slide Title}
    Some text in the main slides
\end{frame}

\note{
   Center this horizontally and vertically
}

\begin{frame}{Slide Title}
    Some text in the main slides
\end{frame}

\setbeamertemplate{note page}[default]
\note{
   switch back to default note
}
%------------------------------------------------

\end{document}
```

Just add `\vfill`s.

    \documentclass[11pt]{beamer}
    
    \usepackage[gen]{eurosym}
    \setbeamerfont{caption}{size=\scriptsize}
    
    \renewcommand*{\thefootnote}{\fnsymbol{footnote}}
    \renewcommand*\footnoterule{}
    \setbeamerfont{footnote}{size=\tiny}
    
    \setbeamersize{text margin left=7mm,text margin right=7mm}
    
    \usepackage{pgfpages}
    \setbeameroption{show notes on second screen=right}
    
    \begin{document}
    
    \begin{frame}{Slide Title}
        Some text in the main slides
    \end{frame}
    
    \note{\vfill
        \begin{center}
            Center this horizontally and vertically
        \end{center}
    \vfill	
    }
    %------------------------------------------------
    
    \end{document}
