The Fullscreen command enables and disables displaying the image window on the entire screen. When it is enabled, the image window takes up the whole screen, but the image stays the same size. When you enable full-screen mode, the menubar may not be displayed, but if this happens, you can right-click on the image to access the image menu. You can set the default appearance for full-screen mode in the Preferences menu.

Pressing TAB key toggles the visibility of all present docks.
