is there a way to tweak the power button in such a way that with one click u lock the screen and once more to unlock it?? instead of twice to lock and then once + swipe? [ like the way using the slider unlock on the right side of the phone does except jut using the power button ]

maybe double click for power button menu and hold for switching off?
btw shortcutd and tweakr dont do the job so dont bother asking to chec those out... tnx
