Hey Traceur,

it was indeed the vi part that i didnt understand.
The new files setup line for the added buttons i had already, but i just didnt know how to get into that rx-51 file.
I notice that some people seem pissed because "noobs shouldnt play with stuff they dont understand", but everyone has to learn, and i WANT to learn about this. And your information was a good start for me!

And indeed, maybe "vi" was to basic for most people, that i oversaw that.

anyways, i want to thank you a lot, coz you really made my day with your help! I didnt expect the whole operation to be fixed within a week, and now it was a few hours!

so thanks again.
