Delete source with remote SAPPHIRE ATI 5000023600

[Chiron]

Good morning

I'm trying to remove some duplicate video sources in kodi, but I just can't find how to do it.
If I could avoid editing with ssh...
I suspect that my remote is not properly set up.
I select the source, and then, what key on the remote shall I press, or more precisely what key code will Kodi expect to remove the entry? KEY_C ? or another?

Thanks to this thread I've been able to fix some buttons (volume up volume down and mute) with codes I've found there in the section SAPPHIRE_ATIUSB_5000023600.

My current lirc file.

Code:

root@xbian:/home/xbian# cat /etc/lirc/remotes/x10-atiwonder.conf
# brand: ATI Remote Wonder
# model no. of remote control: 5000023600
# devices being controlled by this remote: ATI USB Receiver
#
# Found on a linpvr.org forum, thanks.
