You've now been exposed to (pretty much) all of the tools, techniques, and features we used to create the takeTheTrain_Theme.cptm theme that you applied to your project at the beginning of the second chapter of this book. Of course, we could have defined additional Master Slides, inserted more placeholder objects of different types, and defined additional styles. For the sake of time, we will not go any further into defining the theme.
Feel free to open to the final/chapter06/takeTheTrain.cptx file and use the Window | Master Slide menu item to examine the Master Slides, Placeholders, and Styles that we've defined in the theme.
However, there's one additional step that we want to emphasize before moving on to the next topic. To save the newly created styles and Master Slides into the theme, you need to save the theme file itself. By saving the Theme, you update the DiDaXo-Theme.cptm file so that you can apply this theme to other projects....
