With a little help from WIN32API project from VFPx
#define VK_SHIFT   0x10    && SHIFT key
#define VK_CONTROL 0x11    && CTRL key
#define VK_MENU    0x12    && ALT key

DECLARE INTEGER GetAsyncKeyState IN user32;
     INTEGER vKey

lbLoop = .t.
DO WHILE lbLoop 
   CLEAR
   ? "Shift", GetAsyncKeyState (VK_SHIFT)        # 0
   ? "Ctrl" , GetAsyncKeyState (VK_CONTROL) # 0
   ? "Alt"  , GetAsyncKeyState (VK_MENU)        # 0
   lbLoop = INKEY(0) # 27 && Press ESC to exit the loop, press any other key to see the result. To Alt+A, Ctrl+A, Shift+A, only A etc. becuase if you press only Shift/Ctril/Alt Inkey(0) do not work :-)
