How to Emulate hardware menu button I have the Sound Manager app . The app dates back to Android 2.2 and needs a hardware menu button  press to launch its menu .

Can I emulate the hardware menu button on my KitKat 4.4 device , so that I can see the menu?
Apps that could either customize the navigation bar or generate another way of navigation would get it done; however, I've yet to seen one emulating MENU key without requiring root permissions.

LMT Launcher is the app of this type I've been using - it hides a pie-shaped control tray into the edge(s) of your screen that you can activate by swiping from the edge, and contains not just regular navigation keys like BACK, HOME, MENU but also custom keypresses (e.g. POWER) and actions.
