I have opened my PowerPoint Presention within Webex using file>share command. I also am sharing content. How can I quickly navigate or toggle between the two screens? I have to stop sharing the content to see the PPT again. And every time I want to return to the content from the PPT, I have to go to the menu bar >share content>then, either choose the screen or application. Is there an easier way where I do not have to stop sharing the content and quickly view between the presentation and shared content?
