VIM a Powerful Text Editor

VIM a Powerful Text Editor


Vim is a Text editor available in Linux as well as windows and mac platforms.

You can configure it by the following way.


Settings for vim which can be stored in .vimrc in your home flolder in Linux.

These settings are taken from Mr. Mason's webpage, so I am really thankfull to Seth for this wonderful document.
