SEPY : The Ultimate ActionScript Editor

Most heavy-duty ActionScripting is done in external *.as files, and it’s a good idea to use an editor outside of Flash to program in ActionScript. I’ve been using SEPY now for over a year, and it is by far the best ActionScript editor around. Some features include auto completion for Flash functions, a Class browser, Flash MX project file integration, and a snippet panel. Try it today and you’ll never go back.
