In short, \only<>{} does not render the braced material at all except on the named slides, while \onslide<> renders the material until the next \onslide, sort of like an \item, but, on the off slides, covers it (according to the preference given in \setbeamercovered; i.e. transparent or invisible). There are other alternatives, for example, \...

Before looking at how . works, I think it's worth a brief look at how + works as in an overlay specification, and to link that to a 'plain' specification containing only explicit numbers. I'll take the offsets last, as they are more complex. For the simple case of just numbers \begin{itemize} \item<1-> From the first slide \item<2-> From ...

The simplest way is to use the onimage package from the From Answers to Packages project, which implements the answer given in Drawing on an image with TikZ. To use the package: Download the file onimage.dtx from bazaar.launchpad.net/~tex-sx/tex-sx/development/files, run pdflatex on it, and move the resulting .sty file to your working directory. Then you ...

Since you have an untagged environment, you can use \documentclass{beamer} \begin{document} \begin{frame} \begin{align*} \onslide<1->{a &= b \\} \onslide<2->{b &= c \\} \onslide<3>{\Rightarrow \quad a &= c} \end{align*} \end{frame} \end{document} For a tagged environment additional work has to be done, as ...

Just to add another useful package that does it: \usepackage[showframe]{geometry} (as many people load geometry anyways, it is a nice gadget)

\begin{minipage}[t][10cm][t]{\textwidth} will make a top aligned minipage that is 10cm tall.

Use \layout form the layout package. This produces: and prints the layout details on the bottom: \documentclass{article} \usepackage{layout} \begin{document}\layout \end{document}

beamer provides \pause that provides this functionality. You can add that anywhere in the slide and it will "pause" the output there, produce an additional slide for post-pause display. Additionally, many commands typical to LaTeX have been modified in beamer to provide a so-called overlay specification. As an example, the following list show each item only ...

It's a sync problem; if you add \thebeamerpauses in some places (to get the value of the beamerpauses counter), you can see what's going on: \documentclass{beamer} \usepackage[utf8]{inputenc} \usepackage{default} \begin{document} \begin{frame} \begin{itemize}[<+->] \item A\thebeamerpauses \item B\thebeamerpauses \item C\thebeamerpauses \end{itemize}\...

If you just want the boundaries overlaid on the actual pages, independently of other packages, \usepackage{showframe}
