Description

As in the title, is it possible to add something like in https://www.w3.org/Talks/Tools/Slidy2/#(2)

• Font sizes automatically adapt to browser window size
  • use S and B keys for manual control (or < and >, or the - and + keys on the number pad

this function in the revealjs environment?

So that I can immediately modify the font size when there is a problem with the text layout.

That's not a question for Quarto but for Reveal.js.
See https://revealjs.com/ and https://github.com/hakimel/reveal.js.

You could still implement some JavaScript but it might get tricky since Reveal.js is JavaScript already.
