6. Click ADD HYPERLINK. The Hyperlink window is displayed.
   Hyperlink properties are used to apply a hyperlink to the selected element.

   Example:
   
   
   
8. In the Destination URL, enter the following code and include what is required for the subject line.

   WARNING! When you enter your subject line, you will need to add spaces using the %20.

   Since URLs often contain characters outside the ASCII set, the URL must be converted into a valid ASCII format. URL encoding replaces unsafe ASCII characters with a "%" followed by two hexadecimal digits. URL encoding typically replaces a space with a plus (+) sign or with %20.
