Full screen mode
Full-screen mode allows you to use the entire computer screen for browsing. This removes all menus and toolbars from view, but you will of course still be able to use context menus, mouse gestures, and keyboard shortcuts.
Turn full screen mode on or off ¶
To turn on full-screen mode, go to. To return to normal screen view, use the same menu path to deselect it.
Alternate menu path: Ctrl-click the webpage and select "Full Screen" from the context menu
Keyboard shortcut: Option+F11
Opera Show ¶
If a web document is styled for the "projection" media type, switching to full-screen mode turns Opera into a presentation tool. Use Page Up and Page Down to switch slides.
For more information about using the projection media type, see the Dev Opera article, "Creating presentations/slideshows with HTML and CSS".
