Very cool to be able to advance your Slides presentation from your smartphone! Here's how.
Install the Remote for Slides extension from the Chrome Web Store.
You might need to refresh your Slides presentation before the Remote for Slides icon appears.
When you're ready to present, open the web browser on your phone and go to https://slides.limhenry.xyz
Click the Present with Remote button at the top of your Slides presentation.
At the bottom of the screen, click the option to "Show ID and Start Remote." The code that you enter in the area on your phone's browser will appear for only a short time (since audience members could also use the code). Be ready to type it in your phone or jot it down.
