Transitions are a great tool to use for making Objects and Pages appear as you move through your presentation. The default transition is Cut, but you have a number of additional transitions that you can apply.
Adjusting the transition of an Object is as simple as selecting the Object in the Edit Area and opening the Transition Plug-In and choosing the Object Tab. There you can choose the type of transition, additional effects (like direction), and more. The Duration option is how long the transition takes to complete. You can also add a Delay (how long it waits to begin the transition after coming to the page). You can also use Steps to create builds of different objects within a page. For instance, a Step of 0 would show the Object as soon as the Page displays. A Step of 1 would require another advance (F9 for instance) for that object to show. A Step of 2 would require 2 advances. You can then apply the settings to the single object, all objects on the page, or all objects on the cue.
Adjusting the transition of a Page is as simple as selecting a page in the Script and opening the Transition Plug-In and choosing the Pages Tab. There you can choose the type of transition, additional effects (like direction), and the duration, which is how long the transition takes to complete. You can then apply the transition to the selected page, all pages in the cue, or all pages in the script.
As an important note, if a transition besides cut is applied to a page, then object transitions on that page will be ignored (unless they use steps). That means that if you set a dissolve transition for a page, then all objects on that page will also dissolve when they transition.
