You basically just load software on all wanted systems and tell the software where their screens are and you can seamlessly move your mouse from screen to screen and system to system. You can optionally allow it to keep the clipboards in sync too.
I got in on it like 10 years ago as part of a crowdfunding campaign, but they’re still around and look to be relatively reasonably priced.
I use Synergy for the KB/Mouse sharing.
