Currently, it is possible to use JavaScript to create a button to rewind video files within the captivate project, however, there is no similar functionality available for audio files attached to slides. This limitation impacts the learner's ability to revisit specific parts of the audio content.

I recommend adding an option under the interactions section or as part of the timeline settings that enables users to rewind audio attached to a slide. This feature could allow creators to configure rewind increments of 5, 10, and/or 15 seconds(or provide custom intervals). This functionality would make it easier to review the content without having to replay the entire slide.
