A Theme is a file that collects all the formatting properties of a project, including (but not limited to) the Styles. Captivate installs with a handful of ready-to-use Themes right out of the box. In order to have a better idea of what a Theme is, you will start with some simple experiments using the predefined Themes of Captivate. The steps are as follows:
Save and close every open file in Captivate.
Use the File | New Project | Blank Project menu item.
In the New Blank Project dialog, use the Select drop-down menu to choose a size of 800 x 600 for the project. When done, click on the OK button.
Captivate creates a new blank project of the chosen size. When this new project is created, a single slide is automatically added to the Filmstrip panel. This new slide is already formatted and already contains several styled objects.
