How to change the font in Sublime Text 2

Open up your "Base File.sublime-settings" (Preferences Menu → File Settings – User) in Sublime Text 2 Show archive.org snapshot . Add entries for font_face, and optionally font_size, so it looks similar to this:

{
  "font_face": "Envy Code R",
  "font_size": 11.5
}

Cool: when you save the configuration file, changes will be applied instantly.
