Pair Programming

Often while playing the role of an observer during pair programming, I missed the touch of my keyboard and mouse in order to point out something or take control of coding. It was embarrassing whenever I suddenly jerked my pair for his keyboard and mouse.
Well right now, I was introduced this cool application
synergy http://synergy2.sourceforge.net to assist me while pairing.I now share my keyboard and mouse with the my pair. And this way, whenever i want to take control, I can simply use my keyboard and mouse which placed right in front of me. No hustle, No snapping for the keyboard and mouse.
Cheers :)
