How to remote keyboard & mouse, not video?
I probably just do not know the names to search for, so maybe I only need a few words of reply.
What I want to do is control & use my computer while it is 20 feet away, behind the large video display. All hardware will be behind monitor, about 20' from keyboard & trackball.
How can this be done? Can a second computer host trackball & keyboard and connect via Ethernet or 802.11 without also hosting video display?
