Ribbons contain three basic components:
TabsThere are seven of them across the top. Each represents core tasks you do in Excel.
GroupsEach tab has groups that show related items together.
CommandsA command is a button, a box to enter information, or a menu.
The principal commands in Excel are gathered on the first tab, the Home tab. The commands on this tab are those that Microsoft has identified as the most commonly used when people do basic tasks with worksheets.
Groups pull together all the commands you're likely to need for a particular type of task, and throughout the task they remain on display and readily available, instead of being hidden in menus. These vital commands are visible above your work space.Lesson 01: Why learn Excel 2007?
