Control Multiple Computers with Single Keyboard and Mouse
When you have more than 1 computer, it starts to get messy because of the amount of wires and also keyboards and mouse. Normally we have a set of keyboard and mouse for 1 computer and if we were to share it with another computer, there is a small switch box called KVM switch where you can control where you want the keyboard and mouse to be active on which computer. Even KVM uses a lot of wires because you need one input for mouse and keyboard and two outputs or probably more if you want to share it with more computers. Wireless KVM is still not very common and its expensive.

You can try to use Input Director where you can share a single keyboard and mouse with multiple computers. The only drawback is you must have the master computer that the physical keyboard and mouse is attached to turned on and it must have a working network. You switch which system receives the input either by hotkey or by moving the cursor so that it transitions from one screen to the other (in a very similar fashion to a multi-monitor setup). The idea being that you can position the monitors from two or more systems in a row and use a shared keyboard/mouse to control all of them. Input Director also supports a “shared” clipboard, in which you can copy data onto the clipboard on one system, transition across to another and paste.
Input Director is easy to install and configuration merely takes a few minutes. You have to install Input Director on the master computer that has keyboard and mouse attached and also the slave computers. Antivirus or Firewall application can possibly block Input Director from working properly, so make sure you add it to the exclusion list.
