Most programs contain dozens or even hundreds of commands (actions) that you use to work the program. Many of these commands are organized in a ribbon, located just under the title bar.

In some programs, commands might be located under menus. Like a restaurant menu, a program menu shows you a list of choices. To keep the screen uncluttered, menus are hidden until you click their titles in the menu bar, located under the title bar.
To choose one of the commands listed on the ribbon, click it. Sometimes a dialog box will appear, in which you can select further options. If a command is unavailable and cannot be clicked, it is shown in gray.
In some programs, toolbars provide access to frequently used commands in the form of buttons or icons. These commands usually appear in the program's menus, too, but toolbars let you choose a command with just one click. Toolbars typically appear just below the menu bar.
Clicking a toolbar button performs a command. In WordPad, for example, clicking the
Save button

saves the document. To find out what a particular toolbar button does, point to it. The button's name or function is displayed:
