Graham's Macro3 code would be faster than the earlier alternatives of stepping through every paragraph.
I would suggest using InStr instead of .Start to get a bit more flexibility in where the found string might appear.
Code:
Sub Macro4()
Dim oRng As Range
Dim sText As String, sFind As String
sFind = "010" & Chr$(9)
Set oRng = ActiveDocument.Range
With oRng.Find
Do While .Execute(FindText:=sFind)
sText = oRng.Paragraphs(1).Range.Text
If InStr(sText, sFind) = 1 Then
MsgBox sText
End If
oRng.Collapse 0
Loop
End With
lbl_Exit:
Set oRng = Nothing
Exit Sub
End Sub
