Hello Riyad Kalla,
Unfortunately Adobe Captivate 2 does not include a Master
Slide concept, this is something that many of us have requested I
would strongly recommend that you send this as a feature request
using this
form
Whilst this won't work in your situation since you already
have a button object on all the slides in your project one way to
speed up the process of adding objects to a large number of slides
is to do the following
1. Insert the button on the first slide and position it in
the desired location.
2. Choose Edit > Copy
3. Switch to the Storyboard view
4. Select all the slides you want the button to be added to
5. Choose Edit > Paste
This will now automatically add copies of the said object in
the desired location.
Note: Adobe Captivate 2 does include the ability to apply
property changes to all slides in various dialog boxes using the
options available via the Settings button. However it would seem
that this does not enable you to replace an existing button image
with a new one.
Regards,
Mark
