Edison OS-mini remote for changing TV input?

[GezAndJaack]

Does anyone know what Universal functionality the remote for the Edison OS-mini is supposed to have? My TV receives the signal via an Onkyo receiver and I use the Onkyo for volume, but I'd like to be able to choose the TV input, since that is the only thing I need to use my TV remote for now. I've tried doing it out of the box - button TV then button TV Input, but nothing happened. I have a Panasonic Viera.

Oops I had it wrong. The Onkyo remote changes what goes through to the TV - so I'm fine with that. It's actually the TV aspect ratio that I have to use the TV remote for - and I don't expect a universal remote to be able to deal with that, so forget my question!
