• Type in the name for the new Keyword.
• Under the heading, The Keyword applies to...
• Enable the checkboxes of all DayLite Objects you would like this keyword to apply to.

This means that if I select Contacts and Organizations, the keyword can be applied to or an attribute of Contacts and Organizations, but it can not be applied to or an attribute of Projects or Opportunities.
