Ok, I got a bit further by myself:

I added accelerators to the Gtk_Entry widget for all combinations of
Shift, Alt and Control together with return. I use all those
accelerators to send the "activate" signal. This is working just fine
and the handler is called for modifier+return now as well as for return
only.

But how do I get at the pressed modifier from within the activate
handler? My handler gets passed the Gtk_Entry and user data at present.
Adding an event to the handler signature and doing a Get_State(Event)
in the handler does not work: Although the Marshaller does not
complain, it crashes with a STORAGE_ERROR when the handler is called.

What am I missing or overlooking?
