I love the use of cue points when I'm trying to sync specific actions to the audio. It makes it easier to adjust the action if the original timing is off, as compared to" set to XXX Seconds".
Two weeks ago, I held a training session for out eLearning Developers who weren't familiar with Storyline, and when I was introducing them to trigger concept, and how to use the trigger wizard, I used one where I had items changing state when it reached various cue points. The slide I was describing discussed the course features with the navigation and volume controls, along with the Screen Notes, Glossary, Resources, and Menu. When the narration started discussing that feature, I had a larger, brighter icon appear in place of the one on the screen. When it moved to the next item, the icon state reverted back to "Normal".
