            case 'f': Commands.switchViewMode('full'); break;
            case 'g': Commands.switchViewMode('headlines'); break;
            case 'a': Commands.switchViewFilter('all'); break;
            case 's': Commands.switchViewFilter('starred'); break;
            case 'd': Commands.switchViewFilter('unread'); break;
	    
            case 'а': Commands.switchViewMode('full'); break;
            case 'п': Commands.switchViewMode('headlines'); break;
            case 'ф': Commands.switchViewFilter('all'); break;
            case 'ы': Commands.switchViewFilter('starred'); break;
            case 'в': Commands.switchViewFilter('unread'); break;
