Sample Visual Basic Procedure

   Sub SelectEveryNthRow()

       ' Initialize ColsSelection equal to the number of columns in the
       ' selection.
       ColsSelection = Selection.Columns.Count

       ' Initialize RowsSelection equal to the number of rows in your
       ' selection.
       RowsSelection = Selection.Rows.Count

       ' Initialize RowsBetween equal to three.
       RowsBetween = 3

       ' Initialize Diff equal to one row less than the first row number of
       ' the selection.
       Diff = Selection.Row - 1

       ' Resize the selection to be 1 column wide and the same number of
       ' rows long as the initial selection.
       Selection.Resize(RowsSelection, 1).Select

       ' Resize the selection to be every third row and the same number of
       ' columns wide as the original selection.
       Set FinalRange = Selection. _
          Offset(RowsBetween - 1, 0).Resize(1,ColsSelection)

       ' Loop through each cell in the selection.
       For Each xCell In Selection
   
           ' If the row number is a multiple of 3, then . . .
           If xCell.Row Mod RowsBetween = Diff Then
               ' ...reset FinalRange to include the union of the current
               ' FinalRange and the same number of columns.
               Set FinalRange = Application.Union _
                   (FinalRange, xCell.Resize(1,ColsSelection))
           ' End check.
           End If
       ' Iterate loop.
       Next xCell
       ' Select the requested cells in the range.
       FinalRange.Select
   End Sub
