Keyboard shortcuts to blank the screen: Sometimes while presenting in Google Slides you may want to blank the screen during discussion. Simply press B while presenting to make the screen go black, or press W to make it go white. To resume just press any key on the keyboard.
Looping and auto-advance: You can now easily configure a presentation to auto-advance to the next slide while presenting, as well as set a presentation to loop automatically once it gets to the end. This is a simple way to make a slideshow that repeats.
