Synergy is a software for sharing mouse and keyboard between multiple computers on your desk.
It can works well on Windows, Mac OS X and LINUX.
OK, the above information comes from the synergy official web.
Actually it is really a powerful tool if u have many PCs with different OS and u don't want to put several mouses and keyboards on your desk.
But unfortunately, we can't download the latest version from the official web if u don't want to purchase synergy now.
To be frank, 10 dollar is expensive. Then i gooooooooogle the free downloading link and it is lucky i find the downloading link from official web....
I think maybe it is wrong i paste the downloading information here, maybe the web admin will close the FTP access....
/ / U can get all the version of synergy from following FTP
