A tip for presentations: in presentation mode in both Powerpoint and Slides, if you type the slide number and press enter, the presentation will jump to that slide.

If you have notes about which auxiliary slide is relevant to which persnickety comment/topic, you can seamlessly warp to it and it hits harder/makes you look more prepared/polished than a bunch of page up/down and "I know it's here somewhere" filler speech.

I didn't know PowerPoint allows you to navigate that way. I've always used either hyperlinked text or little navigation icons in a corner of the slide to quickly navigate to the relevant back up slides.
