[Q] Remap headphone Skip/Rewind to volume controls?

[seeeejaaaay]

Hello,

I do not own an HTC Sensation, but I recently purchased a pair of the Beats headphones that come with the phone off of eBay. I have remapped hardware keys before, but I was curious if anyone had successfully changed the Skip button on the Headphones to volume Up and the rewind button to Volume down. If so, how would i do this?

Thank you,

CJ
