Presenting a PPT in a window instead of in full screen mode

 Just found a solution to presenting a PPT in a window instead of in full screen mode: 

https://www.csusm.edu/iits/iitsforyou/zoom/zoom-screenmanagement/index.html#:~:text=Get%20PowerPoint%20Out%20of%20Full%20Screen%20Mode&text=Click%20on%20the%20Set%20Up,by%20and%20individual%20(window).

When presenting, just resize the PPT Window. You can then still see the tabs on the opened browser. To switch between the PPT presentation and the browser, press Alt+Tab.
