How it works is very simple, once installed on all the computers, you can hide all the keyboards and mouses except those that are going to act as main controls. After that, we will indicate where the screens are positioned with regard to the main one. Once everything is configured, when the mouse reaches the edge of the screen of one computer it will pass on to the next, this means, if you have two computers and you are using the one on the left, to take control of the right one you will only have to drag the cursor towards it. As if instead of two computers you were working with two screens.
This simple utility saves a lot of time and space, because switching computers is really quick, and all we will need is a keyboard and mouse to control all the computers, without worrying if they use the same operating system or different ones.
