Reclaim

What is Reclaim?

Two machines, one monitor, one keystroke. Reclaim asks the monitor which machine it is showing and sends it the other way, so the same shortcut moves the screen across and brings it home. It works from either machine, because a shortcut does not need a screen. Nothing is installed on the other computer, and it reads both inputs off the monitor itself, so there is nothing to configure. No permissions, no network, nothing to buy. Apple silicon Macs.
