I believe I understand \only<...>{...}
fairly well, but I'm having problems with it. In particular, if \only
comes after the frame it's supposed to be on, the text doesn't appear.
Here is a very simple example:
\begin{frame}
\pause
text
\pause
more text
\pause
even more text
\only<1>{only text}
\end{frame}
The "only text" never shows up. But if I put the \only<1>{only text}
earlier (before the very first pause), then it appears.
Any help is appreciated.
EDIT: By the way, here's what I'm actually trying to get to work. The images at the bottom don't appear.
\begin{frame}
\pause

\begin{lemma}\label{lemma1}
\pause
Fix $\eta:[0,+\infty]\to[0,+\infty]$ for which there exists
\pause $\xi:[0,+\infty]\to[0,+\infty]$ which is convex, pointwise
dominates $\eta$, is finite on $[0,+\infty)$ and vanishes at the origin.
\pause Given $c\in[0,+\infty)$ arbitrary, define $\eta_c:[0,+\infty]\to[0,+\infty]$ by
\pause
%
$$\eta_c(x):=\max\Big\{cx,\inf_{\substack{\mbox{\tiny$\xi$ convex on $[0,+\infty]$}\\
{\mbox{\tiny$\xi\geq\eta$ on $[0,+\infty]$}}}}\xi(x)\Big\},\qquad\forall\,x\in[0,+\infty].$$
%
\pause Then $c\,{\rm id}\leq\eta_c$ on $[0,+\infty]$,
\pause $\eta\leq\eta_c$ on $[0,+\infty]$,
\pause $\eta_c$ is convex,
\pause $\eta_c^{-1}(\{0\})=\{0\}$,
\pause $\eta_c^{-1}(\{+\infty\})=\{+\infty\}$,
\pause is strictly increasing
\pause and continuous.
\end{lemma}

somewhere in a frame, only the text on the frame up to the\pause
command is shown on the first slide..\onslide<1->{text} \onslide<2->{more text} \onslide<3->{even more text} \onslide<1>{only text}
