Remap hardware keys?

So I'm specifically looking to remap the long-press of the home button to the "SEARCH" function, and simply select the Google app. I tried it successfully with the camera button, just changed it from "INFO" to "SEARCH". But that was just to test. I want to remap the long press of the home button but I cannot figure out how to do it. I'm using 4.6.4, rooted via KingRoot. I am editing the "gpio-keys.kl" file, located in /system/usr/keylayout, and here are the contents of the file:
