Icons (shown here) at the top of the Rich Text Editor make it possible to format text in a text box in many ways. Text can be made bold, italic, underlined, centered, bulleted, or numbered. Font styles, sizes, and colors can be changed. Links can be added.
Text boxes also make it possible to add images and tables. (See the Add Images tab for more using on images.)
Advanced users can add search forms and other functions by adding scripts to Rich Text/Dynamic Content/Scripts boxes.
