For the slides, once they are opened, if you would like to print or save them as a PDF, the best way to do this is:
- Click on the icon with three horizontal bars on the bottom left of the browser.
- Click on “Tools” with the gear icon at the top of the sidebar.
- Click on “PDF Export Mode.”
- From there, you can print or save the PDF as you would normally from your internet browser.
- For example, in Chrome: I would click on the 3 vertical dots in the top right corner, then click Print, then change the Destination to “Save as PDF.”
- It doesn’t seem to work well in Safari… Let me know if you’re having trouble.

Here’s a organizational tree that I took from Meike and expanded:
