Aqui está minha solução bastante completa, baseada na solução de Jonas Heidelberg, acima:
Sub ChangeCommentSpan()
'
'If the current selection range is larger than the comment its spans, this macro expands the document-scope
'range of the comment to encompass the entire current selection's range. Alternatively, if the current
'selection range is smaller than the comment spanned by it, this macro reduces the document-scope range of
'the comment to encompass only the current selection's range.
