or modification for logging also deselection:

Case $LVN_ITEMCHANGED
                 $NMLISTVIEW = DllStructCreate($tagNMLISTVIEW, $lParam)
                 ; if state has changed
                 If BitAND(DllStructGetData($NMLISTVIEW, "Changed"), $LVIF_STATE) = $LVIF_STATE And _
                     DllStructGetData($NMLISTVIEW, "NewState") <> DllStructGetData($NMLISTVIEW, "OldState") Then 

                        $Item = _GUICtrlListView_GetItem($ListView, $Index)
                        
                        If BitAND(DllStructGetData($NMLISTVIEW, "NewState"), $LVIS_SELECTED) = $LVIS_SELECTED And _
                            BitAND(DllStructGetData($NMLISTVIEW, "OldState"), $LVIS_SELECTED) = 0 Then
                            ConsoleWrite('selected: ' & $Item[3] & @CR)
                        EndIf
                        
                        If BitAND(DllStructGetData($NMLISTVIEW, "NewState"), $LVIS_SELECTED) = 0 And _
                            BitAND(DllStructGetData($NMLISTVIEW, "OldState"), $LVIS_SELECTED) = $LVIS_SELECTED Then
                            ConsoleWrite('deselected: ' & $Item[3] & @CR)
                        EndIf
                 EndIf

EDIT: corrected: deselection was fired twice

x8 thanks to you Zedna. That's exactly what I wanted. I never had not previously worked with the ListView.
