Synergy lets you share a mouse and keyboard between several computers.. Lets you share a mouse and keyboard between several computers over a network.

Its 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.

Synergy+ Features:
1. Move your mouse easily between computers
2. Requires nothing other than existing ethernet
3. Copy and paste between your computers
4. No need to press any buttons (unlike KVM)
5. You can still use multiple monitors on the same computer
6. Lock the mouse to one screen

Requirements:
* systems must support TCP/IP networking
