# Overlay User Interface

The Overlay user interface is specific to the Colour Corrector and Colour Warper. Its controls are identical to those on the regular user interface except that they are transparent and appear on top of the image. This allows you a greater viewing area when working with large or zoomed-in images.

The Overlay user interface is available when accessing the Colour Corrector or Colour Warper module from the EditDesk or from other modules. It is not available when accessing the Colour Corrector or Colour Warper as a Batch node or as a soft effect.

To toggle between the Overlay user interface and the regular user interface:

1. Press Ctrl+Esc.
   NoteIf accessing the Colour Corrector as a soft effect, you can also use the Player box to toggle between the Overlay user interface and the regular interface options (Player or Triptych).

To hide the Overlay user interface:

1. Press Esc.

In addition to the increased area provided by the transparent controls, you can view even more of your image depending on the action you are performing. For example:

- Panning and zooming in the clip causes the Overlay user interface to disappear completely until the pan or zoom is complete.
- When you play the clip, the Overlay user interface disappears except for the timebar and the current frame number.
- When adjusting a menu parameter, all other user interface elements disappear.

The Overlay user interface does not support multiple views. When you switch to Overlay user interface while using multiple views, your viewport automatically goes to 1-Up until you toggle back to the regular user interface.

When you access a submenu in the Colour Corrector that does not support Overlay user interface, such as Load or Save, the Overlay user interface is restored when you return to the Colour Corrector.

Changing the Look of the Overlay User Interface Buttons

You can adjust the opacity of the Overlay user interface buttons to suit your preference, and even invert the elements in the interface so that white outlines and text appear in a muted grey.

To set preferences for the Overlay user interface:

1. While in the Overlay user interface from the Colour Corrector module, click View.

   The Overlay user interface preferences are displayed.

   If you accessed the Colour Corrector as a Soft Effect, the preferences are displayed in the lower-left portion of the screen.

   Use the Opacity field to increase or decrease the opacity of the buttons. An opacity of 1.0 displays the buttons as they look in the regular user interface. You can also use the following hotkeys.

   Press: | To:
   --- | ---
   Ctrl+Alt+(num pad)+ | Increase the opacity of the Overlay user interface.
   Ctrl+Alt+(num pad)- | Decrease the opacity of the Overlay user interface.

   TipYou can repeatedly press the hotkeys to increase or decrease opacity, or simply hold down the hotkeys until the desired opacity is reached.

   Enable Invert (or press Ctrl+Alt+(num pad)* to switch the Overlay user interface outlines and text from white to grey.
