Just a quick note. For you Mac & Vim users out there - MACVIM. It truly rocks.
Also, a quick "oh my gosh I'm so glad I finally found a command for this," and then a "doh, of course!"
I often launch Vim and then have to work on a set of files in some specific project directly. Its a pain to have to type something like:
over and over and over again. I've been looking for the command to set your 'current directory', and I found it: cd. Duh:
So much better.
