Hey. Figured it out. The answer was more or less staring me in the face.
In the "es_temporaryinput.cfg" there was a line for the hotkey, which I more or less copied.

<input name="hotkeyenable" type="button" id="8" value="1" /> <input name="x" type="button" id="0" value="1"/>

This is my solution. From what I've tested this hasn't messed up anything else even though it does share the
id="0" with one of the axis entries.

Thanks for the input. You can consider this topic "solved".

Thats weird, I did try and delete /home/pi/cfg/default.cfg
it even says it's autogenerated.
Regardless deleting it now it works, thanks a lot :-)
