title: Using volume buttons on Android in Unity3d
body: <p>I am attempting to use the volume buttons in a unity3d game on Android. Unfortunately I can't see anything pertaining to volume being mapped as a KeyCode, so it seems to me that this functionality is absent from Unity3d. Is there a method of doing this that is more hidden? Is there possibly a way to get around this? The application of this is to simply send a UDP packet upon the press of the volume button so it needs not interact with the Unity3d application itself. Possibly a background process that can deal with it? I simply want advice on the path to follow as I don't want to waste time barking up the wrong tree for my solution. Thanks in advance!</p>
