Captivate Classic and built-in Preview
Sorry if this was posted already...
I noticed the "Preview Next Slides" option was still available in the preferences, so I started wondering if Adobe just removed the Preview Next X Slides menu and the (built-in) Preview menu--but not the features.
Sure enough, using the F10 and F4 keys still brought up the built-in previews. Handy for quick checks of the work and not having to render the entire project to view something in the browser.
