Keywords are command line parameters that embed your Action information in an e-mail message. When you select a keyword from the Keywords list, detailed information about it appears in the Keyword Detail box.
You can add keywords to the To, Cc, Subject, and Body fields by:
Selecting the keyword you want to add, and then clicking the arrow button next to the text field.
Typing the keyword directly into the text field. Keywords should be entered in the format ${origin.key}, where origin is an action, source, or event.
