There are two things you can do.
1. The wParam parameter of the message will tell you about the common
modifiers - it'll be a "logical OR" of the state of the shift,
control, etc, keys.
2. You can call the "GetKeyState" message to find out the state of *any*
key at the time of the event currently being processed (as opposed to
"GetAsyncKeyState" which tells you the state of the key *now* ).
