toolbar's functionality can be broken down into the following categories: Show Code, Split, and Design Views: With a click of a single icon, Dreamweaver allows you to quickly switch from design to code view or even a combination of both. Live Data View: When a dynamic page is open in Dreamweaver, the live data view icon appears, allowing you to preview your page as if it were being run from a web server. Title Bar: Allows you to add a unique title to your page. Browser Compatibility Check: Displays a warning icon when Dreamweaver detects that the page structure will conflict with pre-configured target browsers. File Management: Allows you to quickly retrieve from and upload to a remote server. Also provides you with the ability to check into or out of source control (covered with more detail in Chapter 4, "Dreamweaver Site Management." Preview in Browser: This feature will launch your design within a pre-defined browser, allowing you to review your work. Refresh Design View: When in split view, this icon, when clicked, refreshes the design view. View Options: Provides numerous additional view options for both the code and design views. Options include viewing head content, rulers, guides, and more. In code view, these options change to allow word wrapping, line numbers, syntax coloring, and more. Visual Aids: Options available within this menu allow you to control visibility of visual aids, table borders, frame borders, image maps, table widths, as well as various layout block options.
