Once you add Bookmarks to an audio clip, you may want to edit or remove one or more Bookmarks altogether. In PowerPoint, you can’t edit a Bookmark. For example, you cannot change the time position of your Bookmark from 30 seconds to 28 seconds. To achieve this change, you have to delete the earlier Bookmark, and then add a new Bookmark on the time position that you want.
