How to Control Multiple Computers with a Single Keyboard and Mouse
If you have two or more computers at one desk, you don't want two or more sets of keyboards and mice cluttering up your workspace, too. You can buy a hardware gadget that lets you 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. The Synergy application runs on all the computers you're using—the one that has the keyboard and mouse connected and the one(s) that do not—and lets you control all of them from that keyboard and mouse. 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. Synergy also lets you share Clipboard contents between computers. 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.
