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 ...

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

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 ...

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}\...

Simply write \pause before the itemize environment. This will achieve the effect you want.


26

The simplest way would be to use the \only command instead of \uncover. You could also put the formulas into the same \align block, making the code more compact. And as noted in comments, if the element is to be shown on just a single slide, you can simply use \only<n> instead of \only<n-n>. \begin{align*} \only<1>{E=mc^1} \only<...

Here's a possible way to reference overlays by name: \makeatletter \DeclareRobustCommand*{\savepause}[1]{\only<1>{\immediate\write\@auxout{\string\pauseentry{\the\c@framenumber}{#1}{\the\c@beamerpauses}}}} \newcommand*{\usepause}[1]{\@ifundefined{pauses@\the\c@framenumber @#1}{1}{\@nameuse{pauses@\the\c@framenumber @#1}}} \newcommand*{\pauseentry}[3]{\...

Two problems with your first attempt: overlay keyword. Probably you wrote it because you wanted to overlay two figures, but that's not the purpose of this keyword. Inside a single tikzpicture all what you draw is indeed overlayed, by the order in which you draw things. The keyword is used when you want a tikzpicture to be overlayed on the surrounding text ...


22

You can automatically add the overlay number to the file name using the code from Accessing the current overlay number in beamer. If you only want to do this for some pictures, then use like: \tikzsetnextfilename{figure-\overlaynumber} To add it to every picture you could make it part of the prefix: \tikzexternalize[prefix=picture-\overlaynumber-] ...


21

You may be looking for the internal counter \beamer@slideinframe as defined in beamerbasedecode.sty: It is the value beamer consults when encountering something like \only<1,3-5>{...} to check whether to display or to hide the content. A small demonstration on how to access this value: \documentclass{beamer} \makeatletter \newcommand*{\...

2nd attempt (Warning: TikZ 3.0 is required!) Additional filled requirements (see 1st attempt below for all other filled requirements): Allow for "decay" via special prev styles. Each named keyword (such as kw) must provide three styles: kw, special kw and special prev kw. The names of "program counter" (\pc) and its previous value (\pcprev) can be chosen ...

As Andrew Stacey pointed out beamer provides an own \newcommand<> that deals a little better with overlay specification. It is now possible to use \tikzMe{BCD}<+>. As the overlay-specification argument has the delimiters built-in, so changes need to be made to the beameralert style. I opted for two versions; these styles are equivalent: ...

Here's an example of using incremental overlay specifications with offsets. \documentclass{beamer} \begin{document} \begin{frame}[label=integral-of-x]{Example: Integral of $f(x) =x$} \begin{example}<+-> Find $\int_0^3 x\,dx$. \end{example} \begin{solution}<+-> \action<.->{For any $n$ we have $\alert<.(5)>{\Delta x = \frac{3}{n}}$ and ...

Converting my comments above into an answer: In specifying overlay options, you can add the handout:<number> option. For example, \only<1-3| handout:1>{content-1} will print content-1 that appears in frames 1 to 3 as the first page of the handout; \only<4-5| handout:2>{content-2} prints content-2 which appears in frames 4 and 5 as the ...

Add \resetcounteronoverlays{Test} to your preamble \documentclass{beamer} \newcounter{Test} \resetcounteronoverlays{Test} \begin{document} \begin{frame} \begin{itemize} \item Should be 0: \theTest \stepcounter{Test}\pause \item Should be 1: \theTest \stepcounter{Test}\pause \item Should be 2: \theTest \stepcounter{Test}\pause \...

As described by Lionel Mansuy in this duplicate of this question, the following also works: \begin{itemize}[<+(1)->] Note that all <+-> tokens on the same slide also need to be replaced by <+(1)-> for this to work properly.


19

To increase the overlay counter manually (your title), use: \addtocounter{beamerpauses}{X} where X is the number of frames... or \stepcounter{beamerpauses} to increment the counter by 1 For example, you proceed like this: \begin{frame} \stepcounter{beamerpauses} \begin{itemize}[<+->] \item A \item B \end{itemize} \end{frame} Another possibility ...

I can provide you a very basic solution: it is not perfect, but actually does what you wonder. Initially I defined two tikzstyles to characterize whether the block is alerted or not: \tikzset{visib/.style={rectangle,color=blue,fill=blue!10,text=black,draw,text opacity=0.4, text width=#1,align=flush center}} \tikzset{invisib/.style={rectangle,color=gray,...

The second \Alt command in Martin Scharrer's answer is excellent; however, it can cause problems when used with Beamer's incremental overlay specifications (e.g., <+>). This is because Martin's implementation invokes the underlying \alt command using \mathpalette. \mathpalette internally uses \mathchoice, which actually typesets the contents given for ...

Three ways (depending on how you want them to appear, there might be other possibilities): \documentclass{beamer} \begin{document} \begin{frame} \onslide<+->{\begin{block}{block 1} block 1 \end{block}} \onslide<+->{\begin{block}{block 2} block 2 \end{block}} \onslide<+->{\begin{block}{block 3} block 3 \end{block}} \end{frame} \...

This is built into beamer: \documentclass{beamer} \begin{document} \begin{frame} \begin{itemize}[<only@+-+(4)>] \item one \item two \item three \item four \item five \item six \item seven \item eight \item nine \item ten \end{itemize} \end{frame} \end{document} ...

It works as expected if you use \only instead of \visible: \documentclass{beamer} \usepackage[overlay,absolute]{textpos} \setlength{\TPHorizModule}{1cm} \setlength{\TPVertModule}{1cm} \begin{document} \begin{frame} Some text \only<2->{ \begin{textblock}{5}(6,6) Some more text \end{textblock} } \end{frame} \...

Perhaps the simpler solution in this case is to use \only: \documentclass{beamer} \begin{document} \begin{frame} \begin{table} \caption{Table} \begin{tabular}{l c c c c c c} \hline \hline No. & {Ordinary} & {Blue} & {Pink} & {Yellow} & {Green} & {RCM}\\ \hline \only<1>{ &\multicolumn{6}{c}{$\alpha$=0.05}\\ H=2 & ...

I know that this topic is old, but I've tried Roelof Spijker's solution and it has a small drawback. Ideed, the following code: \documentclass{beamer} \usepackage{ulem} \renewcommand<>{\sout}[1]{ \only#2{\beameroriginal{\sout}{#1}} \invisible#2{#1} } \begin{document} \begin{frame} \begin{itemize} \item \sout<2>{World Peace} \...

As usual, these problems can be easily solved thanks to the style visible on defined by Daniel (see Mindmap tikzpicture in beamer (reveal step by step)). Moreover, it works without problems with custom environments. Demonstration: \documentclass{beamer} \usepackage{lmodern} \usepackage{tikz} \tikzset{ invisible/.style={opacity=0,text opacity=0}, ...

When you call a \color<overlay>[colorsys]{color} command that changes the color from then on (within the current group) as it takes as argument only the color specification and not the content that needs to be colored. What happens here is that the sub-itemizes are in their own color environment so they are not affected by your command; instead the ...


16

You need another set of braces: \documentclass{beamer} \usepackage{tikz} \begin{document} \begin{frame} \begin{tikzpicture}[node distance=2cm] \node[align=center] (a) {test 1 \\ {\uncover<2>{test 12345}}}; %wrapped \uncover into {} \node[align=center,right of=a] (b) {test 2}; \path[->] (a) edge (b); ...


16

Sure you can do it. \hypertarget is overlay aware, so you can say something like \hypertarget<4>{label}{\beamerbutton{I'm on the fourth slide}} to place the target just on the fourth slide of a frame and then elsewhere use \hyperlink{label}{\beamerbutton{I jump to fourth slide of next frame}} to activate a button that will take you to the fourth ...


15

Use the overlay specification <+(1)-> instead of <+->, to offset the + in the overlay specification by 1: \documentclass{beamer} \begin{document} \begin{frame}{Test} Some text displayed on all slides in the frame. \begin{itemize}[<+(1)->] \item First item, uncovered on second slide \item Second item, uncovered on third slide. ...

I don't see your problem. I built this MWE: \documentclass{beamer} \usetheme{CambridgeUS} \begin{document} \begin{frame}{Title of this frame} % first block appears at first \only<1>{ \begin{block}{First block} Hello \end{block} } % first block disappears and the second appears \only<2>{ \begin{block}{Second block} Hello ...
