I started using Synergy. This software makes me to be able to share a Mac keyboard and mouse to a Windows machine. For example, when I use a Mac keyboard, I can type a windows machine by using mac keyboard.
I use a HappyHackingKeyboard that is so small but if I put my MacbookAir 11-inch, I feel my desk is too confined to type a keyboard HHKB.
Synergy had some bugs when Mavericks had started available. But now, I can use this normally.
This is a great software!!!
