Preview RemovingToolbar in Full Screen
Using Function-F instead of Shift-Command-F to put the current image in full screen mode without showing the toolbar. The toolbar appears when you are in slide show mode to allow navigation between slides. The Shift-Command-F key combo may once have meant go to full screen. Now Function-F goes to full screen, and does not show the toolbar. I have only checked this in OS Monterey. I suspect it applies to OSs moving forward from Monterey.
