For old-school Microsoft Office users like me, upgrading from Office 2003 to 2007 was a traumatic experience. Microsoft decided to take away our menus and replace them with incomprehensible ribbons – essentially task-based toolbars. It took me 10 minutes to figure out how to insert the date and time.
Finally, I stumbled across a Microsoft website where you can access an Excel workbook that maps the old commands to the various ribbons. You can check it out at http://office.microsoft.com/download/afile.aspx?AssetID=AM101938681033.
