Assuming you have macports install you first type:

port install ctags

Then you generate a ctags file in the root of your Drupal project by typing in:

ctags --langmap=php:.engine.inc.module.theme.install.php --php-kinds=cdfi --languages=php --recurse

type in the following in vim to tell vim to look in the current directory for a tags file and then the parent, and then recursively continue until a tags file is found.

:set tags=./tags; 

Now type in ctrl-] on any function or class name and it will take you to the definition

Here is my .vimrc file for mvim, in particular I don't want to forget how to configure Syntastic for Drupal syntax checking in drupal.  If you type in "phpcs -i" you can verify that the drupal sniffer is setup and available.  The output on my screen from phpcs -i is "The installed coding standards are Drupal, MySource, PEAR, PHPCS, PSR1, PSR2, Squiz and Zend"

* sftp your database dump to the server then

* drush @[site].[env] ah-db-import [/path/to/db/dump/file]

ie: drush @babsoncomm.babsond7dev --uri="dev.bell7.babson.edu" ah-db-import latest.sql --drop

usermod -g group user

This will also allow them to use chgrp to change the group ownership of any files.
