为什么“超级空间”和其他快捷方式有区别？

#1 楼

// Handle super+space when the user is typing in the search entry 
private bool search_entry_key_press (Gdk.EventKey event) { 
    if ((event.keyval == Gdk.Key.space) && ((event.state & Gdk.ModifierType.SUPER_MASK) != 0)) { 
        hide (); 
        return true; 
    }   

    switch (event.keyval) { 
        case Gdk.Key.Tab: 
            // context view is disabled until we get plugins that are actually 
            // useful with a context 
            // search_view.toggle_context (!search_view.in_context_view); 
            return true; 
    }   

    return false; 
}
