How to remap lenovo function keys

[abdurrahman1]

So I just bought a new Lenovo laptop. And of course they went on the current trend of switching to all shortcut keys instead of the fx keys. So of them, so far ive only got the volume up and down and mute keys remapped, but then there's this really tricky mic mute button which has no explicit code. And from my research, there isn't a hexadecimal virtual key code for it either. Is there any way of it? or is there any other alternative to remapping strange shortcut keys?

I have an IdeaPad 720s, they all have the same looking shortcut keys so if anyone could provide codes for all the keys it would be appreciated.

thanks
