Synergy is a software tool that lets you use the same mouse and keyboard on multiple computers in front of you. Simply drag the mouse pointer from one screen to the other! The computers can be different operating systems. (I’m using it right now with my Linux and Windows machines.) Configuring on Windows was a snap: configuring on Linux was slightly more involved, but nothing a computer-savvy user couldn’t do. I highly recommend it if you have multiple computers/monitors but don’t want multiple keyboards and mice on your desk.
