When you insert a Standard Object onto a master slide, and then apply the master slide to a Filmstrip slide, the Standard Object also appears on the Filmstrip slide. You can see the Standard Object, but you can't select it or edit it. If you want to edit a master slide object, you have to return to the master slide, and make the change there. Of course, changing the object on the master slide affects every Filmstrip slide that was using the edited master slide.
Along comes Captivate 6, and making changes to master slide objects while on the Filmstrip slide is now wonderfully possible. Using Placeholder Objects, you can edit the object on the Filmstrip slide, essentially changing just the single slide. And should you regret your action, you can reset the master slide and put everything back to the way it was (like a super, duper undo command).
Instead of inserting a Standard Object onto a master slide, insert a Placeholder Object (Insert > Placeholder Objects), which is only available if you are actively working on a master slide.
Position the Placeholder Object on the master slide as you would any Standard Object. Then, on the Filmstrip, apply the master slide to the Filmstrip slide via the Properties panel.
Once you have applied the master slide to the Filmstrip slide, you'll be able to edit the Placeholder Object directly on the Filmstrip slide. For instance, I inserted an Image Placeholder Object on my master slide. Then, from the Filmstrip slide, I was able to select the Image Placeholder Object, insert an image, move the object around my slide and re-size it.
Best of all, I was able to reset the slide. After inserting an image into the Placeholder Object, I accidentally re-sized and moved the object from its original master slide position. Instead of re-resizing and dragging the object back to its original position (or using the Undo command multiple times), I simply clicked the Reset Master Slide button (shown in the image above), and the object instantly returned to its master slide size and position--on its own. In a word, this is an awesome, often overlooked, feature!
