Two computers, one keyboard (and mouse) program

[bminer1]

Is there a program out there like Share Mouse that is compatible with Linux (raspberry Pi) and Windows?
My desktop sits right by my pi and having one keyboard on the desk is the goal.

I did look into that and it seems to be the only program available. I just dont want to spend $30 for it. thats the only thing that sucks. Share Mouse is free but doesnt support Linux.
