vi

vim autocomplete, or really, autoexpand abbreviations

All about shortcuts as well as abbreviations: http://www.linux.com/archive/articles/54936

To set abbreviations only for insert mode (which seems a little safer) add to your .vimrc file (or in Agaric's case, an included .vimrc-agaric file with all our Drupal and other development-specific additions) abbreviations in the format iab abbr abbreviation.

To store your Vim settings in a different file (Agaric does this so that we can put all our "custom home" configuration type files easily in version control together) use the source command.

In .vimrc to include other file:

source /path/to/file/morvimconfig

In ben-agaric's case, the entire .vimrc file is only:

source /home/ben/customhome/.vimrc-agaric
