Use rollover captions when you want to display the caption only when the user moves the mouse over a designated area on the slide. Rollover captions consist of a caption and a rectangle that marks the designated area, also called the rollover area. The caption appears when the user moves the mouse over the rollover area at run time.
Rollover captions and rollover images consist of a caption or image and a rollover area (the “hot” area). The rollover area defines where the mouse must be for the caption or image to appear.
To change the size of the rollover area, click one of the handles and drag.
To move the rollover area to another location, move the mouse over the rollover area until the hand cursor appears. Drag the box to the desired location.
To modify the rollover area attributes, select the rollover area make the required changes in the Property Inspector (Window > Properties).
Customize the following for the rollover area in the Property Inspector if required:
Stroke Stroke color for the rollover area.
Fill Fill color for the rollover area. To decide the degree of transparency for the fill color, select a value for the option Alpha in the Color menu. The value of 90% is less transparent (more solid) than a value of 10%.
Width Thickness of the border of the rollover area.
Fill Outer Area Select this option to fill the area outside the boundaries of the rollover area with the color selected in Fill Color. When you choose this option, the area within the rollover area is not colored.
You can observe the fill color around the rollover area only when you preview or publish the project.
The other tabs in the Properties dialog box are similar to those for text captions. See Text captions for more information.
When you record a new project or record additional slides for an existing project, you can set a recording option that requires Adobe Captivate to convert tooltips to rollover captions. When this option is selected, Adobe Captivate creates a rollover caption for every tooltip that is selected during the recording process.
Converting tooltips to rollover captions is an easy way to automatically create an appropriate and descriptive caption for action taking place in a project.
