How to capture 3 different keys in a OnKeyDown event?

[brsk]

Hi, I'm currently working on a proyect at my job, and I'm having trouble trying to capture 3 different keys at the same time. I have no issues when I try CTRL + K or CTRL + L, however on this case I need to capture CTRL + K + L in order to open a popup window.

My last attempt was the following:

void __fastcall TBCFrm::FormKeyDown(TObject *Sender, WORD &Key, TShiftState Shift)
{
if (Shift.Contains(ssCtrl) && Key == "K"' && Key == 'L') {
//Open popup window
}
}

Does anyone know if there is a way to combine these 3 keys?

Thanks
