I am a limited user of Libre Office. In trying to print a spreadsheet sent to me via email I clicked on full screen on the Libre tool bar and now I need to know how to restore the tool bar.
Unfortunately, I don’t have a Mac, so not sure if this makes sense, but here’s a key shortcut used on other systems:
To toggle full-screen view: Ctrl+Shift+J
Also, there should have been a one-button floating toolbar, clicking on that would return you to normal view.
