Here’s another one for Mac OS.
You can switch between Virtual Desktops using this keyboard shortcut.
Ctrl + Right Arrow
to go right.
Ctrl + Left Arrow
to go left.
Please note that this works only for the monitor/screen that has been selected.
To give more context, unlike in Windows, in Mac OS Virtual Desktops are dependant on the monitors/screens.
To gain focus of a screen merely having focus on an application is not always enough, you must click your mouse on that screen to gain mouse focus (I made up this word).
So, when you use the above shortcuts, you move between Virtual Desktops of the selected monitor only.
Note: I’m using MacOS Monterey
