There is no built-in way to determine what procedure called
another. The only way would be to create a public variable, put
the caller's name in that variable, and read that variable in the
routine.

[in module1]
Public WhoCalled As New Collection

Sub AAA()
WhoCalled.Add "AAA"
' more code
End Sub

[in ThisWorkbook]
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
Dim CalledBy As String
CalledBy = WhoCalled(WhoCalled.Count)
Select Case CalledBy
Case "AAA"
' do something
Case "BBB"
' do something else
Case ....
End Select

End Sub
