Synergy
Have you ever had two different computers side by side and wished
you didn't need 2 mice and keyboards? I have. A while ago I coincidentally came across
Synergy. This cross-platform tool allows one to control several computers with 1 mouse and 1 keyboard. Bonus: it's completely
free.
My Debian laptop is sitting to the right of my dual monitor Win7 setup
and I can now effectively use it to browse internet, as well as
copy-paste code to and from it. Yes, you heard it right, Synergy allows
to
share the clipboard between the systems.
