#1 Leopard application of the day (Free)
Synergy is a great application and a must have for those people with more than one computer at their desk. Basically, Synergy is a KVM but done through software. This means that you can use the same mouse and keyboard across all your multiple machines, even if one is windows, one is mac, and one is linux.
From the developer’s site:
Synergy lets you easily share a single mouse and keyboard between multiple computers with different operating systems, each with its own display, without special hardware. It’s intended for users with multiple computers on their desk since each system uses its own monitor(s).
Redirecting the mouse and keyboard is as simple as moving the mouse off the edge of your screen. Synergy also merges the clipboards of all the systems into one, allowing cut-and-paste between systems. Furthermore, it synchronizes screen savers so they all start and stop together and, if screen locking is enabled, only one screen requires a password to unlock them all. Learn more about how it works.
