Windows does not pass it to hook function.

QM installs keyboard hook procedure which intercepts keyboard messages when Windows posts them to active window. Windows does not notify active window about some keys: PrintScreen (44), Alt+Tab, global hot-keys registered by other applications, etc.

Macro programs use low-level function keybd_event to simulate key press so that it goes through Windows.
