Certain Keys Disabled - Exile Mod

[DeadNed 0]

Does anyone have info on why certain keys are disabled or not able to be bound in Exile mod?  Insert. Home. End and Delete can be bound but do not seem to function.  Also is there anyway to rebind holster weapon from 4 to something else?  I have tried auto hotkey which always worked for games like Fallout 4 but does not seem to have an impact with A3 Exile.  A3 Epoch I was able to use these keys. I am guessing it is something with the way Exile mod was written?
