Triggers are text or images that have a special DHTML effect applied. When users click text or an image that's assigned a trigger, a target appears. To open DHTML effects using triggers, first assign a trigger to text or an image. Then connect the trigger to a target and assign a DHTML effect. When working with triggers and targets, keep in mind the following details:
•Triggers and targets must reside in the same topic.
•To indicate that an item is clickable, change the font color and underline, or add text to an image.
