I'm displaying page numbers in a beamer document using this:
% my ``own'' boadilla, i.e. without the infolines
\usecolortheme{rose}
\useinnertheme[shadow]{rounded}
\usecolortheme{dolphin}
\setbeamertemplate{footline}[frame number]
and page numbers generally show up, as I want. But on some slides, when the text is written all the way to the bottom, page numbers are hidden, since they are probably "beneath" the level of the text. But since the text is usually on the left and the page numbers are on the right, I want the page numbers to show through. I don't know what to search for since I think of this as "overlay" or "beneath" or "under", but those words all have several meanings and I can't get the one I want. In web design terminology, what I want to do is change the "zIndex" of the footer. Any ideas? Thanks
\begin{frame}[plain]and this, obviously, prevents the page number from showing. So answer solved! thanks – Stephen Apr 2 '11 at 21:56
