MSDN：
nFlags
Indicates whether various virtual keys are down. This parameter can be any combination of the following values:
MK_CONTROL Set if the CTRL key is down.
MK_LBUTTON Set if the left mouse button is down.
MK_MBUTTON Set if the middle mouse button is down.
MK_RBUTTON Set if the right mouse button is down.
MK_SHIFT Set if the SHIFT key is down.
你可以实现一些功能如：
if(nFlags & MK_CONTROL) //处理ctrl键被按下消息。。
if(nFlags & MK_MBUTTON) //处理鼠标中键按下的消息。
等等

组合键标记，可以实现一些相对比较丰富的功能
