Overlays - How to show an item from for x slides startin from the current overlay?

Question

Using beamer's overlay I want to gradually show the items of an itemize environment. However some of the items are supposed to only show for say 3 slides. How do you do this?

In my understanding this should look something like

\only<.-3>{some text}

So starting from the current overlay (.) this should show up to the third following slide (-3).

Answer 1

I guess you are looking for <.-+(2)>. In detail this means:

• . the text starts to be visible on the current overlay

• - until

• +(2) the next to next overlay (the two overlays plus the frame where the text starts to be visible make then 3 overlays in total)

\documentclass{beamer}

\begin{document}

\begin{frame}
\only<1>{1}
\only<.-+(2)>{some text}
\only<4>{4}
\only<5>{5}
\end{frame}

\end{document}
