Using the HTML Editor
You can set your user preferences to allow you to use the HTML editor in the Send Email dialog box. For more information, see Outbound Communications Preferences for Send Email.
In your application, you might come across various screens in which you can invoke the HTML editor. The HTML editor provides special editing controls that allow you to use supported HTML formatting, and also provides some standard editing features, such as cut and paste.
It is recommended that you use CTRL+Enter to move to a new line using the HTML editor. Doing so avoids empty rows.
