Synergy works between any number of PC, Mac, and Linux desktops. If you copy information to the Clipboard on one computer and move your mouse to the other, you can paste it there, even though they’re two different systems. Synergy also lets you share Clipboard contents between computers. That means you can move your mouse off one computer’s screen and it will appear on the other, where you can type and work as well. The Synergy application runs on all the computers you use - the one that has the keyboard and mouse connected and the one(s) that do not - and enables you to control all of them from that keyboard and mouse. You can buy a hardware gadget that enables you to share a single keyboard and mouse with several computers (which involves a mess of tangled wires), or you could use a free software solution called Synergy.

If you have two or more computers at one desk, you don’t want two or more sets of keyboards and mice cluttering up the tabletop, too. Hack 121: Control Multiple Computers with a Single Keyboard and Mouse
