Preview documents in target browsers at any time by choosing File > Preview in Browser, or by pressing F12 or Shift-F12 to display the primary or secondary browser, respectively. Previewing opens the current document in a browser. You do not have to save the document first. All browser-related functions work, including JavaScript behaviors, links, ActiveX controls, Netscape plugins, and so on, provided that you have installed the required plug-ins or ActiveX controls.

Choose File > Preview in Browser > Edit Browser List to define a primary and secondary browser. You can define up to 20 browsers for previewing. All the browsers you define appear on the Preview in Browser submenu.

(Content linked to a site root-relative path does not appear when you preview documents in a local browser. This is because browsers don't recognize a site-root when opening a local file. To preview content linked with root-relative paths, set up a local server and use the Preview Online option (Windows only), or put the file on a remote server to view the page in a browser. See also About relative and absolute paths.)
