Macdrifter has a few posts up about how he uses Sublime Text 2 which contain some great tips and hints. My favorite?
Want to edit all occurrences of a word at once? Select the word and hit ctrl-⌘-G. Now start typing. All occurrences of the word will be selected and edited simultaneously. Forget Find-and-Replace, this is better.
I knew about selecting the next instance of a word to edit (⌘-D) which is shown in the first movie on ST2’s homepage but I did not know how to select them all. Cool!
