Search for font in Keynote?

Hi.

I've discovered that my classroom computer does not have a couple of fonts that Keynote thinks I have in some of my presentations.

I would like to see where this font appears before changing it, so I can be sure it looks right. Is there any way to search for instances of a font? I've paged through the presentation with no luck, so hoping there is some other way to do this.

Thanks in advance for any advice.

(i have most recent Keynote on my home machine running Sonoma)
