Back in 2007, I thought Microsoft's "ribbon" interface was terrible, blaming it for slowing my productivity to a crawl as I hunted for commonly used tools and options. Since then, the ribbon evolved and Redmond worked out most of the kinks, and I'm happy to admit that my opinion was founded on resistance to change, rather than the merits of the interface.
Microsoft now extends the ribbon concept to the Mac version of Excel 2011, like it has for the Apple-flavored iteration of PowerPoint. Power users and newcomers alike can master the basics of the interface by reading CustomGuide's quick reference guide to Microsoft Excel 2011 for Mac, available for download in the IT Downloads library.
It describes the Excel 2011 screen layout, explains the fundamentals of using the application, lists keyboard shortcuts, shows you how to insert charts and offers instructions on working with formulas and functions.
