Here's how I have Nova Launcher Prime set up: Single press home button-> Go to home screen, double press home button-> launch Google search (same as pressing the magnifying glass on older Android phones), long press menu button-> launch Google Voice Search, double tap home screen-> launch S-Voice, swipe up on home screen-> launch app drawer, swipe down on home screen-> expand notification bar.
