[Q] A13 Capacitive Touch Buttons

[Ilithis]

I was wondering how one enables the touch keys in a ROM for the Menu, Back, and Options buttons. I have tried editing the sun4i-keyboard.kl file to include the entries for these virtual keys and enable the tkey_para section of the script.bin but they still won't function. In the original ROM the sun4i-keyboard.kl file did not have the virtual keys listed, but they worked on the original ROM. Any idea where I can look to map these keys?
