Geek post! 🙂 There are a few utilities that I use that are not well known, but I find critical. One of the ones that I use most is Synergy. It’s function is straight-forward: share one mouse and keyboard among multiple computers. What makes Synergy awesome, though, is how far above and beyond this functionality Synergy goes. First, it’s cross-platform: I use it to share between my Linux workstation and a Macbook Pro seemlessly. Second, it supports clipboard sync – e.g. copy some text on the Macbook and paste it into a window on the Linux workstation like they are the same system.
Synergy is software for sharing one keyboard and mouse between multiple computers.
