If you are among those who have multiple machines on their desktop, then you
must be familiar with the problem of goofing up with the keyboard and mouse. You
start typing and suddenly
realize that the keyboard which you are using is not the one intended. Also,
multiple keyboards and mice eat up a lot of desk space. In case of KVM Switch,
it reduces the number of monitors as well, along with keyboards and mice. And
sometimes, sliding between multiple machines just to see if your compilation is
done seems annoying. A small tool called Input Director solves the problem by
allowing you to control multiple Windows systems with only one keyboard and
mouse on the Master PC. You can download it from http://www.in putdirector.com/.
Once the download and installation is done, run the application on the your
master PC.

Go to ‘Master Configuration’ tab (as shown above) and specify the number of monitors to be controlled from the master computer.	Now go to the ‘Slave Configuration’ tab and add the host name of slave computer and the number of monitors connected in it. Don’t change the port settings.

Here, select, if you want to allow any machine act as a master to take control, or a specific series of IP or a specific machine.	Now come back to the master machine. Here in the Master configuration you will see the added node. Drag and drop the machines in the white box to set the layout of your display.
