Is switching between multiple computer screens possible?

I really like Extended Desktop, where the two displays a are concatenated along an edge to form one larger Extended Desktop. just move the mouse in the direction of the other display and it moves to the other display, once you have correlated the positions in physical space with the presentation in arrangement:

Alternatives:

If you are a big user of Mission control, and use Mission Control to create different 'Spaces' for different groups of tasks, you can extend that concept to include 'Displays have separate spaces'. you use the regular 'spaces' shortcuts to move between spaces, they are just on different displays.

If just switching between screens connected to the same computer, there's nothing you need to do; the same kbd & mouse work across all of the connected screens.

It sounds like you want to switch the keyboard & mouse between screens on different computers. Is that what you are asking about? If so, you would need a KVM switch.

That's not jumping or switching screens ... that's switching between open applications. Use CMD-Tab to switch from one open app to another. It doesn't matter which screen (display) they are on.

Then all you need to do is select the other Chrome pane/tab/window by clicking on it with your mouse. The behavior is the same as when you have two Chrome widows open on the same display.

In Extended Desktop mode, as in your case, the keyboard & mouse work across the entire set of displays as if they were one.
