It has nothing to do with the sequence, but the fact that sequence will never appear in the current paragraph, because of ^p which makes the search across two paragraphs. Use instead
Code:
Sub Macro2()
Dim oRng As Range
Dim oPara As Paragraph
Dim sText As String
For Each oPara In ActiveDocument.Paragraphs
Set oRng = oPara.Range
With oRng.Find
Do While .Execute(FindText:="010^t")
If oRng.start = oPara.Range.start Then
sText = Replace(oRng.Text, Chr(9), "")
'do something with stext e.g.
MsgBox sText
End If
oRng.Collapse 0
Loop
End With
Next oPara
lbl_Exit:
Set oRng = Nothing
Set oPara = Nothing
Exit Sub
End Sub
