Thanks Stefan,  I've got it now.  I should be looking at widgets and I 
guess all the widget stuff applies to all and sundry that is derived 
from widget.

// Variable declarations

    GtkWidget    *name; //name refs File/Open or Edit/copy etc

// In builder stuff added

    name = GTK_WIDGET (gtk_builder_get_object (builder, "Open")); // if 
called Open in Glade.

// In program (the part that's actually executed).

    gtk_widget_set_sensitive(name, FALSE); // or TRUE as needed

Thanks a million, it's working great. Regards Ian.
