How to Make a VirtualBox Machine Go Fullscreen

Oracle's VirtualBox virtual machine manager program runs guest operating systems inside the operating system on your computer. Each guest operating system has its own virtual hardware and normally runs in a window on your desktop. You can also use a virtual machine in full-screen mode, covering up the rest of your desktop. You can switch to full-screen mode using a menu option or a keyboard shortcut, but you can only exit full-screen mode with the keyboard shortcut.
