In this section, you will discover three more objects. These objects are known as the Rollover Objects. They are originally hidden and show only when the user rolls over a specific area of the slide with their mouse. This behavior makes the Rollover Objects impossible to use on touch devices such as tablets and smartphones. This is the reason why the Rollover Objects are not supported in HTML5 and will not be used in the project you are working on.
Nevertheless, these objects are an excellent addition to any flash-based project and are still an important part of Captivate's toolset.
