I've been a BBEdit user for a decade, and despite my switch to Zend Studio last fall for the bulk of my PHP development, I still find myself going to plain text editors for little tweaks, or less formal "hack it out" efforts.
There are a few things that I've grown very accustomed to as a Zend Studio user over the past several months. One of those is typing "/**" in a PHP document and having a full phpDocumentor docblock appear magically, with the cursor insertion point set on the first line of the comment area.
Unfortunately, TextMate doesn't handle it quite that way, but he's found a similar way to accomplish it - using "doc_cp" followed by a TAB. It doesn't quite handle the preformatted blocks as well as Zend's software does, but that's nothing the scripting features of TextMate can't take care of - he shows you how.
