The feature described in this Help topic is only available if support for a right-to-left language such as Arabic or Hebrew is enabled through Microsoft Office Language Settings.
In addition, you must be running a Microsoft Windows operating system that has right-to-left support — for example, Microsoft Windows 2000.
When you change the paragraph direction, Microsoft FrontPage leaves justified and centered text as it is. In the case of left-aligned or right-aligned text, FrontPage flips the alignment to its opposite. For example, if you have a left-to-right paragraph that is right-aligned, such as the date at the top of a letter, clicking Right-to-Left results in a right-to-left paragraph that is left aligned.
About tabs in right-to-left documents
The tab direction follows the paragraph direction — for example, when you change a left-to-right paragraph to a right-to-left paragraph, the left tabs become right tabs, that is they are repositioned relative to the direction of a paragraph.
