What are the virtual key codes for the Windows 8 specific multimedia keys?

Question

I have a Microsoft Sculpt Ergonomic Desktop which has additional function keys.

See also my question on SuperUser, "What are the functions of the multimedia keys?".

There are keys for the charm bar functions and some I have yet to identify.

Since Windows 7 does not have these functions I thought I could write an application to do something useful with these keys.

What are the virtual key codes for these keys?

Answer 1

I figured it out on my own using a simple test application:

F5  = Search                         = 16 91 132 = VK_SHIFT   + VK_LWIN + VK_F21
F6  = Share                          = 18 91 132 = VK_MENU    + VK_LWIN + VK_F21
F7  = Devices                        = 17 91 132 = VK_CONTROL + VK_LWIN + VK_F21
F8  = Settings                       =    91 132 =              VK_LWIN + VK_F21
F9  = Display switch                 = 17 91   8 = VK_CONTROL + VK_LWIN + VK_BACK
F10 = Flip3D
F11 = Horizontal display orientation = 18 91 133 = VK_MENU    + VK_LWIN + VK_F22
F12 = Vertical display orientation   = 17 91 134 = VK_CONTROL + VK_LWIN + VK_F23

F10 invokes Flip3D on Windows 7, so without installing a keyboard hook I can not figure out what key combination is triggered.
