Displaying text after specific number of slides for a particular frame
When using beamer class if we have used itemize with item<1->, item<3->, etc. and after itemize if we try to display something after last item when itemize is over with \pause then that message starts coming from second slide onwards and not after last item is displayed. This is probably because itemize maintains its own slide count which is different from \pause counts.
Hence we can enclose message to be displayed on nth slide onwards in
\uncover{n-}{message}
when we want to specify slide number after which the message should be displayed.
