Format Ruby code in Vim

Question

Just moving over to Vim at the moment. In TextMate I could format code by hitting Cmd-Alt-[. How do I achieve the same in Vim?

---

See the answer below for the command. I found I also needed the following in my .vimrc so that Vim knew how to autoindent Ruby.

if has("autocmd")   filetype indent on endif
