A family of Microsoft word processing software products for creating web, email, and print documents.
There is no automatic method to align the body text lines when they're mixed with headings, lists, and other items that have different line heights and paragraph spacings. You'll have to make manual adjustments, mostly to the space before and after the headings and list items. That will have to be done after all editing of the text is complete; otherwise you might have to make additional adjustments.
Also, if the document is transferred to another computer that has a different default printer driver, the spacings (mostly between characters, which may affect where line endings occur) might change.
You may find some of the recommendations in http://wordfaqs.mvps.org/BottomLine.htm to be useful.
