Okay, so you mean "NextSrc" on the knob-press menu (it also exists in [ir-translate]..).. Well, that works just fine for me, on both a Mk2 and Mk2a, with and without a Tuner.

Too bad for you.

And the PopUp0 requires that you add a line to your config.ini, and the example I originally posted said "Visuals" on that line, which is an error, it should have said "Visual". Fix that, and it also works fine.
