I am a huge fan of Sublime Text, which is my code editor of choice. Jeffrey Way from Nettuts+ thinks the same way and he really knows everything you have to know about this amazing editor. There have been already some articles on Nettuts+ about Sublime Text, but this time Jeffrey has done a whole course on it, including all the tricks you really need to know to perfect your workflow. If you're already a ST addict, take a look if there are some tricks you do not already know. If not, take some time and check it out too. You won't regret it!
