Synergy: Control multiple computers with one keyboard

Syngery is a nifty little app that allows you share the keyboard and mouse with other computers on your desk. It’s available on Linux, OSX and Windows. Obviously, this application is useful for people with more than one computer on their desks but should come in handy for those with a laptop and a desktop on the same desk, as well. Basically, this application allows you to move your mouse from one computer screen to the next, using the local network and the keyboard is active for the computer where the mouse cursor is currently on.
