Multi-Language Demo: Shift on the fly, single-threaded development

I know there are many ways to do this, and I've seen some demonstrated in eLearning workshops and conferences, but if anyone is looking for a way to create a single thread of slides (vs. branching), I created a demo (and blog post) describing everything.

• To see it in action, here's the working demo (created in Storyline 2, but can also be done in Storyline 1).
• Here is the source Storyline file.

The description was long enough that I didn't want to repost the entire thing here, so if you'd like to see how it was done and the steps involved, check it out here.

Questions and comments always welcome. I hope this is useful to someone. :)
