Disable mouse scrolling in xaringan presentation

Question

I am making slides using xaringan in RStudio and on my Mac, the magic mouse scroll is too sensitive and basically makes using my mouse as a pointer very difficult. Is there a way to disable mouse scrolling?

A remark.js issue here suggests that it might be possible. I tried using the issue linked above to include the css chunk

{css}
var slideshow = remark.create({
  navigation: {
    scroll: false
  }
});

but not being too familiar with javascript and css I'm not sure exactly what else to try. Does anyone know how to achieve this within xaringan?

There's no need to fiddle around with JavaScript here. All you need to do is to set scroll: false in the YAML header under output: like this:

output:
  xaringan::moon_reader:
    lib_dir: libs
    nature:
      navigation:
        scroll: false
