My issue is not with Office 2007 or Office 2010. As I noted in my first reply I found the commands and could add them to my customizable took bar. The issue popped up when I found these commands are not in Office 2011 For Mac. I don't know if this is an issue only with the Mac or if this is a future direction with Office products in general.

Is Microsoft going to provide the Back and Forward commands in future Office products (including Office 2011 For Mac)? This is the issue.
