"123" Key Code
I'm trying to map the 123 key of my remote, the one just below the power button, see this [link](https://images.eprice.it/nobrand/0/Lightbox/926/207402926/AF9673B1-C883-4EB0-9A28-E93F56DFDD91.jpg) for reference, but I can't find anywhere the key code associated with it (if it even exists). Is anyone been able to remap one of the remote control keys to this specific button? 

Thanks in advance
