Capitvate editing question...please help.

Hi - I have recorded audio and slides for a presentation I gave using captivate.  I need to edit the audio and would like to keep the slides in sync.  How can I do this?  I am able to edit the audio, but that puts the slides out of sync.

1. How can I divide/split a recorded slide?

2. Is it possible to simply cut out audio and "video"/parts of slides at the same time?

3. I can shorten a slide from the back end, can I shorten it from the front end?

Thanks for the help,

John
