There are multiple links to various instructions for MS Word. While you indicate the 2013 version and that formatting is a prime issue, http://guides.lib.umich.edu/word2010 may be of immediate help. I know the link indicates Word 2010 but, the site reflects 2013 as well. In any case, most of the formatting issues of past versions of Word apply to 2013.

Other links that may help:
http://shaunakelly.com/word and http://addbalance.com/word/. Of course, there are many more...

Hope this helps.
