Beamer: \nonumber equivalent for slides?

Question

Is there an equivalent command to \nonumber when one doesn't want to include certain slides in the numbering? I would like to leave outline and title slides out of my numbering, and instead just number slides with actual content. Other workarounds would be nice to know about as well.

Edit: Since a MWE example was requested, here is one. Suppose I have a title page and two other slides. The code below gives a slide counter that goes up to 3, and the title slide is slide 1. I would prefer to have the title slide not be numbered, the counter go up to 2, and the the numbering start at the slide after the title. Here is some code.

\documentclass{beamer}

\mode<presentation>
 {
   \usetheme{Dresden}
 }

 \setbeamertemplate
 {footline}{\quad\hfill\insertframenumber/\inserttotalframenumber\strut\quad} 


\begin{document}

\begin{frame}
 \titlepage
\end{frame}

\begin{frame}
Some actual content here
\end{frame}

\begin{frame}
Some more actual content here
\end{frame}

\end{document}

Answer 1

Since beamer version 3.08, there is an undocumented option noframenumbering that doesn't increase the slide counter for the frame it is used on. This has the advantage that you don't have to manipulate the framenumber counter by hand. It is used like this:

\begin{frame}[noframenumbering]
 \titlepage
\end{frame}

Answer 2

I usually just modify the framenumber counter using \setcounter to reset the frame number and \addtocounter with e.g. -1 to compensate for a slide which should not count. Usually you also want to hide the frame counter for these slides.

For example I used the following to don't number the title frame:

\begingroup
\renewcommand{\insertframenumber}{}
 \begin{frame}
  \addtocounter{framenumber}{-1}
  \titlepage
 \end{frame}
\endgroup

One issue with the frame number hiding is that theme use something like \insertframenumber{} / \inserttotalframenumber and so you can't get rid of the / that easy. I copied my theme for the lower bar and replaced that part with an own macro \insertframenumberratio which I set to empty to suppress the display. Alternatively you can still display it which then shows the number of the next slide. Usually people won't notice or mind that.

Answer 3

\documentclass{beamer}
\setbeamertemplate{footline}[page number]{}

\begin{document}

{\setbeamertemplate{footline}{} 
\begin{frame}
\titlepage
\end{frame}
} %this removes the footline from title page

\addtocounter{page}{-1}  %the next frame will start from number 1 instead of 2
...

\appendix %all the frame after this line will not be included in the TOTAL PAGE count
%your appendix frames go here   
\begin{frame}{References}
...
\end{frame}
\end{document}

Answer 4

For this specific example, I would just relocate the definition of the beamer template - \setbeamertemplate - to after the first slide. Additionally, for the framecounter to be accurate (using Martin's answer), add \addtocounter{framecounter}{-1} at the same location:

\documentclass{beamer}

\mode<presentation>
 {
   \usetheme{Dresden}
 }

\begin{document}

\begin{frame}
 \titlepage
\end{frame}

 \addtocounter{framenumber}{-1}
 \setbeamertemplate
 {footline}{\quad\hfill\insertframenumber/\inserttotalframenumber\strut\quad} 

\begin{frame}
Some actual content here
\end{frame}

\begin{frame}
Some more actual content here
\end{frame}

\end{document}​
