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.
After initial prodding from Tim over at Armenian Eagle and a little from Zach at NoSheep!, I have downloaded Synergy and installed it on my work computers, a Dell Latitude and a Mac. The software is sexy as it allows me to use my mouse and keyboard (both wireless) on either machine without swapping out cables. Now, whats sweet about it is the fact that not only am I able to move my mouse and type from computer to computer, but I can also copy-paste from one machine to the other! Hugely useful.
The setup isn’t overly intuitive but its not too difficult. Synergy is available for Windows, OSX, and Linux…so if you’re sitting with multiple keyboards and mice, its time to make the switch.
