After you have created an object, you can copy that object and paste it onto the same slide, a different slide in your project, or several slides in your project at the same time. This can save you a great deal of time, especially if you create intricate objects with specific sizes, colors, and formatting.
Opomba:
You can also copy and paste objects between different projects.
Opomba:
To reuse media objects that appear in the Library, simply drag the object from the Library onto the slide.
When objects from a slide are copied into a slidelet, the following properties of the objects are modified:
If timing for the object is specified as Rest Of Slide or Rest Of Project, it is changed to Rest Of Slidelet.
The option Synchronize With Project loses its validity for FLV files.
You can copy and paste objects from other projects. This strategy can save you a great deal of time. For example, suppose you have created a detailed object in another project. Simply copy and paste the object into any new projects you create.
Opomba:
To reuse media objects from another Adobe Captivate project, open that project Library from within your current project Library. Then drag objects directly onto a slide or into the current project Library for easy reuse.
Opomba:
You can also copy Advanced Actions and Shared Actions associated with the objects. To do so, copy the objects referenced from within these actions in addition to the parent object to which the actions are assigned.
Duplicating objects is an easy way to reuse content. For example, you can duplicate a detailed caption and change some of the text to quickly add more information to your project.

In Update 2 of the 2019 release of Captivate, you can copy and paste the appearance of one object to one or more objects. The workflow is similar to the Format Painter feature in MS Word, where you can copy the style of a text or an object and apply the style to other objects without creating a style.
Using this feature, you can quickly apply similar formatting, such as color, font style and size, and border style, to multiple pieces of text or objects.

Like copying and pasting text styles, you can copy the styles of an object and paste them to a second object.
To copy and paste the appearance of an object, follow the steps below:

As with text and objects, you can copy the appearances of the states in a button and paste to that of a second button. The new button will have similar looking appearances to its states as that of the source button.

For the second, if you navigate to its state view, you can see that all states that were defined for the first button are now copied to the second one.
States for the buttonOpomba:
If you add a Custom state to the first button and apply the style to the second button, the visited state does not get copied to the state of the second button.
