Disable Wake From Volume Buttons (ROOT)

I like having keys that have specific jobs.  There is something that just feels a little sloppy to me when multiple keys have the same effect. In this instance I'm talking about multiple buttons that wake the phone from sleep. The home button and power button make sense to me, but I just don't need those volume buttons doing the job too. For that reason, I've disabled that option.
 I used Root Explorer on my Galaxy S2 but there are other options. First navigate to the root folder and then to: system/usr/keylayout. Open the sec_key.kl file as a text document and then just delete the word "WAKE" from the lines you want. Each line corresponds to a button on the phone, it's clear you'll see. Save the file and reboot. Done. You will need to root your Galaxy S2 first. I really ought to do a quicksticks root guide.... coming soon.
