To check if a key was pressed when you process a mouse message,
(GetKeyState(key) & 0x8000) /* for example, key=VK_SHIFT */

This will get the state of the key *when the current message was
generated*. If you need to know whether it is pressed right now, use
GetAsyncKeyState().

If you need instead to check the state of the mouse button(s) when
processing keyboard messages, you can use:
(GetKeyState(VK_LBUTTON) & 0x8000)
(GetKeyState(VK_RBUTTON) & 0x8000)

Note: these will return the state of the *physical* left and right
buttons, which will be reversed if the user has switched them in the
mouse control panel.

I define macros to avoid scattering code with constants, and to get a
1 or 0 result:

#define WAS_PRESSED(key) ((GetKeyState(key) & 0x8000) != 0)
#define IS_PRESSED(Key) ((GetAysncKeyState(key) & 0x8000) != 0)
