A few years ago, I found a tool to share the keyboard and mouse of one computer with another computer. That looks like this:
As you can see, the tool also runs on any platform not only Windows.
Today I have two laptops on my desk and thought about that great tool. Now I found it again. It is called “Synergy” and can be** [downloaded for free here**](http://synergy-foss.org/). The author updated it and it works very well.
The configuration is farely easy:
On the computer with the keyboard and mouse, start the tool, click “Configure Server” and you will get this dialog:
There you can drag computers around your existing one where they physical are placed.
Now save and click start.
On the other computers select “Client” and enter the hostname or IP address of the host computer. Done.
