Jump to Slide. When you accidentally back up over an animation-rich slide, you can simply jump over the slide rather than stepping through each build using the bracket keys.
Swap Displays. In presentation mode, X toggles the display and presenter screens while in presentation mode. Handy for those tense first few seconds where it’s not clear which display is showing up where.
I use Keynote all the time and I had absolutely no idea that those gems existed. The first one is particularly useful, as I often fudge the navigation and my poor students have to sit there (im)patiently while I stab the arrow keys to get back where I should have been.
