Restricting Keynote to secondary screen
With online teaching suddenly becoming the norm, I'm finding an issue with Keynote that I can't resolve. In regular classroom teaching I use a secondary monitor with my primary monitor showing the Presenter display. However, when sharing my secondary screen in one of the online teaching platforms, I would like to choose to not show the Presenter display so that I can use the primary screen to see other things, like student chats.
I have not been able to find a way to do this, other than exporting my Keynote file to HTML format, then showing it in a browser. It would be great to have a toggle in Keynote preferences to choose whether the Presenter screen is displayed, allowing you then to toggle it off and use the screen for other things.
