In this case – Mouse without Borders – a little utility I have been using for a while that enables you to use a keyboard and mouse across multiple machines and screens. You can have mouse that moves from one machine to another (even when you have multiple monitors, different Windows OS’s) and then have the keyboard just work on the other machine.
when I am doing demo’s (or even just when I am working from home) I have multiple laptops set up and it is handy to be able to use one central keyboard when going from machine to machine. It works over IP so I have had an odd incident at home where I had a laptop in the lounge room and the mouse and keyboard had gone off the screen – in fact onto the laptop that was in the office
It also allows copy and paste and even drag and drop between the machines – very handy!
