Formatting text in the Advanced HTML Editor is very similar to other standard applications.  You can easily modify the font size, heading type, and add bold, italics, or underlines to your text.  You can also choose between left, center, right, and full justifications. 

Addtional formatting tools in the editor include creating numbered lists and bulleted lists, as well as adjusting the tab position, formatting the color of text or the background color of text, and inserting special characters or seperators. 

The binocular icon in the editor tool bar is a simple search & replace feature for global text changes within the page you are editing as well.
