AT THIS POINT pressing the down arrow button one more time will get you to the RECEIVERS... button. Press the right arrow button and BOOM, you're in the screen you couldn't find before.

Oh, man. There it is! I've been up-and-down-and-over-and-out of that screen so many times, yet I've never found this before. Mystery solved, and I've been an idiot. Thanks TF (and Peter) for persisting to help me!

I will sleep like a baby tonight...
