The event fires when the user presses the menu button.
document.addEventListener("menubutton", yourCallbackFunction, false);
Applying an event handler overrides the default menu button behavior.
Applications typically should use document.addEventListener

event fires.
document.addEventListener("menubutton", onMenuKeyDown, false); function onMenuKeyDown() { // Handle the back button }
