The buttons at the top of the HUE Intuition window let you control how your live video appears on-screen.
Hide Controls makes your video area larger by hiding all of the on-screen buttons and borders. You can still use the keyboard shortcuts to take snapshots. Windows users can hide the controls instantly by pressing F12 on the keyboard. On macOS, the option can be accessed by pressing Shift+H.
Full Screen/Windowed toggles between displaying HUE Intuition full screen and in a window. The shortcut is Ctrl+F on Windows or Cmd+F on macOS.
Pressing the Escape (Esc) key will always restore the default view.
