beamer overlay: carry text over from previous slide

Question

This code

\documentclass{beamer}
\begin{document}
\begin{frame}
  \begin{overprint}
    \onslide<1>
    Text on slide 1 and 2
    \onslide<2>
    Text on slide 1 and 2\\
    Text on slide 2
  \end{overprint}
\end{frame}
\end{document}

creates the output

As the phrase

Text on slide 1 and 2

is used both on slides 1 and 2 I have to repeat it 1 time. Wouldn't it be so much better if I could carry it over from the previous slide and then just append

Text on slide 2

to it.

Is it possible?

Answer 1

Sure, that's what the \pause command does.

\documentclass{beamer}
\begin{document}
\begin{frame}
  \begin{overprint}
    Text on slide 1 and 2\\
    \pause
    Text on slide 2
  \end{overprint}
\end{frame}
\end{document}
