[HELP][REQUEST][TOOL] How to discover map code of keys in keyboard?

[JohnnyWolinger]

Hi @RehabMan, im trying to patch keys of my notebook (Acer F5-573G-50KS) to adjust brightness up and down, i tryed to discover code of keys, i know its _Q8F to Down and _Q8E to Up brightness dimmer. But i cant find code of 0x???? of this chars. And what term of this code? 0x????. Hexadecimal? I used ioio to try discover but not worked. Using VoodooPS2 kext, Im using this patch:

// Brightness Patch Keys
into method label _Q8F replace_content
begin
// Brightness Down\n
Notify(\_SB.PCI0.LPCB.PS2K, 0x0205)\n
Notify(\_SB.PCI0.LPCB.PS2K, 0x0285)\n
end;
into method label _Q8E replace_content
begin
// Brightness Up\n
Notify(\_SB.PCI0.LPCB.PS2K, 0x0206)\n
Notify(\_SB.PCI0.LPCB.PS2K, 0x0286)\n
end;

I think this value 0x0205, 0x0285, 0x0206, 0x0286 its incorrects to my keyboard. You have a tool or can create a tool to show this codes? Will be help some peoples with this doubts. Please move to correct section if i posted wrong. Thanks.
