Multiple desktops/Mission Control
With MacOS you can have multiple desktops running at once. Multiple desktops can have different open applications on them. For example, you can have email and Word running on one desktop, and another desktop just have a gaming application open.
The multiple desktop feature is called Mission Control. To run Mission Control, Access it from the Launchpad or the Applications list in Finder.
When Mission Control is running, a bar will appear at the top of the screen to provide you a management interface. By default there will be two items, Dashboard and Desktop. Dashboard is a collection of commonly used utilities like Calculator, Calendar, and Clock. Desktop is your current desktop. To add another desktop, click on the plus sign on the right of this bar.
To switch back and forth between the desktops, press CTRL-LEFT ARROW or CTRL-RIGHT ARROW.
