# Control SuperSource

### **Parameters**

* **SuperSource ID**: The SuperSource to edit. Default is 1.
* **Action**: The action to perform on the SuperSource. Choose from Swap Boxes, Highlight Box, or Reset Layout.
* **Box**: If Highlight is chosen, enter the box index of the box you want to highlight.
* **Box A**: If Swap Boxes is enabled, enter the box index of the first box you want to swap.
* **Box B**: If Swap Boxes is enabled, enter the box index of the second box you want to swap.

If Box A and Box B are left blank, and if there are only two boxes visible on-screen, running this action will cause the two boxes to swap their video sources.

Choosing Reset will reset the current layout to the last used one on the device.

### **Returns**

Nothing.
