When I edit a slide show it easy to copy whole slides in `Working` Screen Environment but nice to preview slides in `SlideShow` Screen Environment.

*Mathematica* has convenient interactive buttons to go to Full Screen mode and change slides.

**Is it possible to set up an easy button or hot key to switch between `Working` and `SlideShow` Screen Environments to avoid trips to menu? Maybe using `DockedCells` ? Any similar ideas ?**
