Final answer:
Pressing the Main Screen key typically returns the display to the primary UI of an application. In simulations, it can bring you back to a navigation overview showing important metrics like your distance from the Sun while navigating space.
Step-by-step explanation:
Depending on your hardware, you may use the Windows Logo Key + PrtScn button as a shortcut for print screen. If your device does not have the PrtScn button, you may use Fn + Windows logo key + Space Bar to take a screenshot, which can then be printed. One of the most common keyboard shortcuts for switching between multiple monitors is Win+P, which opens a menu that lets you choose how to project your display.
You can select PC screen only, Duplicate, Extend, or Second screen only. When the Main Screen key is pressed, it typically restores the display to the primary user interface or dashboard of an application or operating system. In the context of navigating through a virtual space or simulation, pressing the Main Screen key might return the view to a central navigation screen.
For instance, when navigating through screens of "empty space" in a simulation that involves exploring the solar system, pressing the Main Screen key could bring you back to an overview where your current distance from the Sun is displayed, often together with other vital statistics or controls for the navigation through the simulated environment.
