Started using vi, although the only reason is it being light weight [I am taking a leap of faith, hoping that it will increase my speed after some practice, as most vi gurus say]. Let me first admit it. Vi feels awful in the beginning. It is really intimidating, and I am having a hard time to remember the commands and stuff. Hence I started writing the commands I learn from google and stackoverflow in a file. Thought to post it here, for everyone.

I will keep the list updated as I learn more and more commands and tricks. It serves me as a reference, and hopefully will do the same for some of you.
