When you click an icon, the code may appear in your page immediately, or a dialog box may appear requesting more information to complete the code.
To find out what each button does, position the pointer over it until a tooltip appears. The number and type of buttons available in the Insert bar varies depending on the current document type. It also depends on whether you’re using Code view or Design view.
Although the Insert bar provides a collection of frequently used tags, it is not comprehensive. To choose from a more comprehensive selection of tags, use the Tag Chooser.
