Yes, the Word doco on this is lacking. You could use:
Code:
Sub Test()
Dim myRange As Range
Set myRange = ActiveDocument.Range.GoTo(What:=wdGoToLine, Which:=wdGoToAbsolute, Count:=6)
Set myRange = myRange.GoTo(What:=wdGoToBookmark, Name:="\line")
myRange.Select
End Sub
but, when you see what's selected, you'll realise the range often doesn't span the entire line.
