There is another special sign you can use in an overlay specification that behaves similarly to the |+|-sign: a dot. When you write |<.->|, a similar thing as in |<+->| happens \emph{except} that the counter |beamerpauses| is \emph{not} incremented and \emph{except} that you get the value of |beamerpauses| decreased by one. Thus a dot, possibly followed by an offset, just expands to the current value of the counter |beamerpauses| minus one, possibly offset. This dot notation can be useful in case like the following: \begin{verbatim} |
