Default [Searching] Wakeup Code without getting to home screen [AOSP]

Hey guys,

im searching for this code / gerrit code review :

When you are using Touchwizz for example and your screen turns off and you instantly hit the home button, the screen turns on WITHOUT leading you to your home screen, it stays where it was before.

Im using an AOSP Rom which hasnt got this function and my Rom DEV cannot find it anywhere. So im trying to help him with opening this thread, to get this legendary thing in it ( I think CM got this implented too )

Thanks in advance !
