A family of Microsoft word processing software products for creating web, email, and print documents.
If you click on the Show\Hide button (¶), does each line terminate with a ¶?
If so, you could use:
Dim i As Long
With ActiveDocument
For i = 1 To .Paragraphs.count
With .Paragraphs(i).Range
.Text = "H" & Mid(.Text, 2)
End With
Next i
End With
replace the "H" with the new character that you want as the first in each line.
