Can't seem to find the + key in karabiner elements.

[hamzamousleh bassam]

Hi. My Apple magic keyboard is drunk, and keeps pressing the + sign on it's own. I'm trying to find the key in the simple modifications option, but can't seem to find it. I can only find the keypad version (Numpad), but that doesn't turn it off. Does anybody know where i can find it. 

If you have a creative soul, and can find another solution to turning the key off completely, then it's much appreciated. 

Thanks in advance
