How to see WordPress sidebar links and settings by turning off Gutenberg Full Screen Mode
Did you loose the WordPress toolbars on the left and top of your screen? Here's a quick video how to turn that back on and manage your settings for a page.
Transcript:
I'm going to do a quick demonstration of how to turn off full screen mode for the Gutenberg editor. What you're seeing right now is the standard Gutenberg editor. If you click on these three dots in the upper right corner, this will open up your options and you can turn off full screen mode. Doing this will give you access to the WordPress dashboard up at the top as well as the sidebar, so you can more easily navigate throughout WordPress.
The other thing you can do is click on this gear icon to open up the settings for the page. You can expand and collapse these sidebar widgets. And this will give you access to do things like publish the page, move the page to trash, update the URL. You can add a parent page under page attributes. All this good stuff is hidden in this little gear icon here.
