The Book's search function works pretty well for most search terms: http://web2py.com/book/default/search?search=beautify
T() is for translating text into other languages. I typically advise new users to not use it in the beginning, especially if you have no intention of translating your site. I would highly advise going through the first 8 chapters of the book and especially chapter 3: http://web2py.com/book/default/chapter/03
