This system includes some more advanced techniques using variables to simulate a 'navigate device' button.

I use three variables that stores a '3 bit' value when you select a source, and then with a press/hold on a 'system' button will send you to a different device for a quick setup, such as preamplifier sound field selections, a lighting page or whatever. Then pressing the [back] button on that page, you will be sent back to your previous device.

The concept is that you don't have to put a lighting page on all your devices, you can jump to that device page, and then go back to your previous device with one button press.
