I'm trying to make a touch proximity keyboard (capacitive touch) with the QT2160 IC (as it is the only IC I have). I only need 8 buttons. I have already mapped out a PS/2 Keyboard and have its circuit board/chip.

2 of the keys that I am trying are combination/chorded keys (for example, Ctrl+V).
How do I design the circuit so that a touch on one electrode registers as 'Ctrl+V'?
How do I utilize the QT2160 for this project?

Thanks for your help.

I did that. I don't have a electronic background, and the pdf looks a little confusing in terms of the circuit. I get almost all of it except like i mentioned how to do the chorded keys and what the circuit should look like...just a simple example would be sufficient.
