Code conversion can be done via the 'Encoding' menu of the application, so writing code in Unix or Mac format is just as easy, especially thanks to the extensive support for a plethora of character sets and programming languages. To help those who prefer automating tasks, specially repetitive ones, this utility will enable you to record, save and run macros.
