Disabling AutoComplete for Two Columns

I am doing some transcription work and I'm wanting to disable AutoComplete cell values for columns F & G. I have Excel 2007. I found the following code and changed "A" to F but I can't figure out how to disable column G as well. Surely there's a way to do this. I appreciate any help anyone can give me. Thanks in advance.

Private Sub Worksheet_SelectionChange(ByVal Target As Range)
    Select Case Target.Column
'       Disable for column A - change to suit
        Case 1
            Application.EnableAutoComplete = False
        Case Else
            Application.EnableAutoComplete = True
    End Select
End Sub
