BT keyboard not registering some Fn keys!

[bootsector]

I've bought this BT mini-keyboard to use with MiSTer:

Everything seems to work great EXCEPT for function keys F3 through F6 not registering at all on MiSTer, either by Main or the showkey utility on Linux shell.

Related non-Function keys from 3 through 6 work fine though.

I've paired the same BT keyboard with my Linux machine and I've got correct key codes for F3 - F6 keys with showkey utility.

I wonder if MiSTer Linux kernel is doing some king of "filtering" on those keys?

@Sorgelig, any chances of making this permanent in MiSTer's kernel image?
