The screenshot example shows how to setup the "Media" button. This button is allowed to be redefined to start any app you want. Maybe you can see, that only three of all sixteen(!) available extra buttons like Play, Stop, Record and – our target here – the "Green Button" aka Media Center Button in the lower, right corner of your diNovo Mini Keyboard are available. Furthermore the other two buttons even do offer less options to redefine them. How can we modify this gratuitous constraints?
