How to create tabbed screencasts

Im creating a series of how-to videos(screencasts) for my startup. I was wondering if anyone has experience with tabbed video content.

An example is: http://services.google.com/training/websiteoptimizeroverview/2995095/index.html

I really love how the user can click straight to what he/she is needing help with.

I've been using Camtasia but it does not have this capability.

Any ideas or suggestions are welcome.
