Forgive me if this is already answered elsewhere (if so,I can't find it). I want to record a video of a keynote presentation (including animations and embedded audio and video) and switch several times between me as the presenter and narrator on the webcam. But as soon as I play the presentation it fills the whole screen and the Snagit controls disappear. There is no 'window in window' option for Keynote. Hope someone can help.
