Delete smartshape copies

With the exception of objects on master slides, each object needs to have a unique ID in order to be able to address it with actions like Show./Hide, Change State etc...

You show a dropdown list in the Advanced Actions dialog box, probably because it is almost impossible to target the correct object when keeping the generic names. That problem is due to the fact that an advanced/shared action is able to target all objects in a project, contrary to the simple actions where lot of commands are limited to the objects on the same slide.

First recommendation: label all objects you want to use in advanced actions. Have a look at:

Why would you want to delete smartshapes as mentioned in the topic title? Can you explain?

When using a good labeling system you can also take advantage of the Filtering functionality of the dropdown lists:

What you need to understand is that every object in a Captivate project must have a unique ID.  So, whenever you add a new SmartShape or Image or Text Entry Box or any other type of object, the Object Name will be different to any of the others.  Captivate enforces this to make them all uniquely identified.

So although you might think that all of those SmartShapes that are listed in the drop-down menu are just copies, they are in fact individual Smart Shapes that exist somewhere in your project.

If you want to know exactly where they are and what they are used for, then you need to get into the habit of naming each object you add to a slide so that the Object Name is more meaningful and explanatory.  That will make the objet you want to manipulate with Advanced Actions easier to find when you are looking at these lists.
