Vim quick reference

The following content is excerpted from It covers most of the essentials that one needs while editing code. One thing which i know and use and is not covered is :e < filename > to open multiple files without exiting vim and then navigating among the open files using :b < num > , where num is file buffer number for the open files . Other than that, there were quite a few points in the tutorial that were really good and i did not use/know them before. Also see other good links to learn more on vi/vim at
