You are probably looking for some kind of WM_HOTKEY message that will either be from VK_TBACK or some other soft button like VK_TSOFT1 or VK_TSOFT2 this is all implemented by your device manufacturer, so you have two options:

Option 1: Implement a keypress reporter and everytime a button is pressed on the device it will report to you what the programmatic name of the key is.

Option 2: Contact HTC and ask them how they implemented their keyborad driver and how it reports back button presses.

Otherwise you can hunt around in MSDN until WM 8 comes out and you may not find an answer.

I think if in the emulator if you hit a hardware key you will get a list of events for when a direction key is pressed... I THINK .... you might be able to capture keyboard input on this.. stick a breakpoint on that method and see if it fires and is ignored when a keyboard key is struck... you might then just need to get the ID/Index of that key.
