Hi, RobiNew! Just replace selection with ActiveDocument.range:
Code:
Sub Macro()
Dim oRng As range
Set oRng = ActiveDocument.range
oRng.Find.ClearFormatting
With oRng.Find.Font
.Superscript = True
End With
oRng.Find.Replacement.ClearFormatting
With oRng.Find.Replacement.Font
.Superscript = False
End With
oRng.Find.Execute Replace:=wdReplaceAll
End Sub
Note that this is the fastest replacement.
