This is a feature in Keynote, and I believe it’s possible in PowerPoint as well. In Presentation mode, it would be useful to be able to use right-click to go back to the previous slide (in the same way that left-click advances to the next slide).
I use a wireless mouse when I present. In Keynote, I constantly use right-click to go back, because I’m often not close to the computer. This is what prevents me from switching to Figma Slides.
This is mostly a feature request, but I’m open to alternative solutions that would solve my problem.
