synergy
Allowing one keyboard and one mouse controling multiple PC’s. Very nice! You used to have to do this with a hardware configuaration. This software goes on the “to do on a rainy day” list.
The software is called synergy and their web site says:
synergy: [noun] a mutually advantageous conjunction of distinct elements
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
