Собственно сабж.
Нужно описать сообщение onMouseMove при зажатом шифте.

Дополнительный вопрос: как написать, какая при этом зажата мышь - левая или правая?

Второй вопрос остается в силе, как в описании WM_MouseMove написать "если зажата правая/левая мышь"?

The GetKeyState function can be used to check the down state of the following virtual keys:

VK_CONTROL VK_RCONTROL
VK_LCONTROL VK_RMENU
VK_LSHIFT VK_RSHIFT
VK_LMENU VK_SHIFT
VK_MENU
The key status returned from this function changes as a specified thread reads key messages from its message queue. The status does not reflect the interrupt-level state associated with the hardware. Use the GetAsyncKeyState function to retrieve that information.

An application calls GetKeyState in response to a keyboard-input message. This function retrieves the state of the key when the input message was generated.
