Working on Rails code for a bit has started me on the spiral into obsessively customising my dev environment (I say obsessive as at the last Rails meetup I went to there was some guy who was raving about shaving milliseconds off each line of code and therefore upto half an hour a day... I hope I don't become that guy...)

I spend most of my time in TextMate so it seemed like a great place to start the optimising... So far I've added a few TextMate bundles like Git Bundle, Project Plus and the theme from Railscasts.

I've noticed some of the other TextMate users I've come into contact with using heaps of nifty keyboard shortcuts and other plugins to help make their dev environment more friendly.

Looking around the net, I was a bit overwhelmed by the amount of shortcuts and plugins available... So I was hoping to hear from other Rails developers out there:

What are some good keyboard shortcuts and plugins that I should be aware of for TextMate with specific reference to Rails Development?

I've read this question on SO: http://stackoverflow.com/questions/99807/what-are-some-useful-textmate-shortcuts but I was wondering if there was something a bit more specific to Rails development.
