I don’t want to encourage anyone, but if you are interested in customizing your vim editor, check out Learn Vimscript the Hard Way.
“The book is divided roughly into three sections:
- The first covers basic Vim commands that you can use in your
~/.vimrcfile to customize Vim quickly and easily.
- The second looks more deeply at Vimscript as a programming language, covering things like variables, comparisons, and functions.
- The third walks through the creation of a sample plugin intended for distribution to other Vim users.“
