What are the KeyCode Enums for mobile devices?

I've been trying to add mobile support to my isometric shooter, but I cannot figure out what the KeyCode Enums for mobile devices are. I'd like to know what they are for the thumbstick, mainly. Although other KeyCodes may be useful in the future.

I've checked the wiki, did quite a bit of searching and trying whatever KeyCodes I could find, but so far nothing has worked. Any help is appreciated.

They dont have keys. Or buttons. They have touch, and special events for touching, as well as accessing the gyroscopes and accelarometers.
