I've started a new project where we use MacBooks, IntelliJ, and Maven. Being a Windows (or Linux), Eclipse, Ant guy, I'm out of my comfort zone on several levels.
OK, so one question at a time. In Eclipse, you have the ability to hit a button called "Link with Editor", which shows you where the file currently open in your editor exists in the project hierarchy. That's pretty useful for complex projects. I'm sure IntelliJ can do the same thing, but how?
