In my dissertation defense presentation (Beamer/TikZ), I have a particular slide with a model, built as
tikzpicture, wrapped in a
scalebox block for zoom control. It works fine.
However, I would like to reuse this diagram's code in another slide further in the presentation to display a smaller version of the same model (along with a text block) for reference, in order to avoid the need to navigate multiple slides backward and forward again. This is quite important, because: 1) I plan to use a presenter device (remote), which makes such transitions not feasible; 2) I don't want to abruptly switch the context and disrupt the flow of my presentation.
Ideally, I would like to define the model as LaTeX variable and refer to it in both places with different zoom levels, using
scalebox. Is such reuse possible and, if yes, how could I do that?
