First, you will have to select the app you wish trigger from the home button. You can adjust the duration between two taps, but the default normal setting works fine. Now select the default launcher you use, which will be triggered whenever you tap the home key just once. Finally, select Home 2 Shortcut as your default launcher by tapping “always” option when you hit the home key next time.
