A very powerful tool for text manipulation under *nix systems is VI [Short for Visual]. I started using some 5 years ago, and it rapidly became my favorite text editor of choice under linux/unix and I use it on the windows platform too as gVim.
I’m not going to start explaining its power, I just want to share a VI cheat-sheet I found a few months back when I was working for Faculte.
The first image is the entire Cheat Sheet, and the rest are the training sheets for different actions you want to perform while text editing. So? How do you like it?
