You can insert HTML or script inside the contents of a text box at the insertion point, for example, to add text attributes or comments to the HTML. Note that you cannot do this in HTML Code view.
In Page view, double-click in the text box to get an insertion point.
From the Text menu, choose Insert HTML.
The Insert HTML dialog appears.
Enter your HTML or script.
The Insert HTML dialog can contain up to 255 characters. To insert more than 255 characters, use the HTML Code Editor or Object HTML dialog or reference an external HTML file.
Click OK.
Preview the page to test your code, and view the source from your browser to see the resulting HTML.
