what are the input codes for Sony Xperia Play keys?

Are there going to be input key codes for the Xperia Play by Sony?

Left Hand: Left, Right, Up, Down Left Shoulder

Right Hand: Triangle, Circle, Cross, Square Right Shoulder

Function: Select, Start.

And RAW data from the "thumb tabs"?

Here's a pic for anyone not familiar with a PS controller. http://www.eurodroid.com/pics/xperia_play_2.png

Not a full answer but the only information I found so far:

How to develop gaming apps using the Xperia PLAY gamepad

Also, using Input.GetKey("left") works (as does "up", "down" and "right", of course).

But aside of that, I'm hoping to get some more info soon ... because trying to figure out the keycodes via:

public void OnGUI() {
    if (Event.current.isKey)
        Debug.Log(string.Format("Key pressed: {0}", Event.current.keyCode));
}

didn't work for me :-(

Xperia Play Keycodes in Unity

Input.GetKey (KeyCode.LeftShift) = Left shoulder
Input.GetKey (KeyCode.RightShift) = Right shoulder

Input.GetKey (KeyCode.UpArrow) = Up
Input.GetKey (KeyCode.LeftArrow) = Left
Input.GetKey (KeyCode.RightArrow) = Right
Input.GetKey (KeyCode.DownArrow) = Down

Input.GetKey ("joystick button 2") = /\
Input.GetKey ("joystick button 1") = []
Input.GetKey ("joystick button 3") = O
Input.GetKey ("joystick button 0") = X

Input.GetKey (KeyCode.Pause) = SELECT
Input.GetKey (KeyCode.Return) = START

AndroidInput = TouchPad

Oh... and rumors has it that an official tutorial is landing in the Asset Store at some point.
