Switching control between host and KVM's guest VM

With a Linux host (e.g. Linuxx Mint) running VirtualBox,
when inside the guest VM, to switch from guest VM to host,
press right-side Ctrl (this transfers control to host), and then Alt+Tab
to display host’s GUI list of running user apps to view.

But if your visualization is KVM, what is the corresponding solution?

What hot keys to use for switching control between host and KVM’s guest VM when you are inside the guest VM’s terminal?


I am aware we can use mouse, but I am looking for hotkey combinations… i.e. strictly command line.

Also if you know where the specific documentation for this is, that would help a lot.
I have been look, but no luck.

Thank you.
