I'm entering this discussion a little late, so I apologize if I'm
misinterpreting your question but ...

When using WM_LBUTTONDOWN, checking the value of wParam will determine the
state of the shift, control, and middle or right mouse buttons.  Basically,
wParam will be the union of things like MK_CONTROL, MK_RBUTTON, MK_SHIFT,
and MK_MBUTTON, so check for those.

Hope this helps.
