title: IntelliJ Idea 10: how to turn off auto-complete in .txt files
body: <p>I've just upgraded to IntelliJ IDEA 10, and it has started doing something extremely annoying. While writing documentation in a .txt file it has started giving me word suggestions as I type. This is, instead of helping, just irritating me while also consuming system resources. I haven't been able to find a way to turn this off in the Settings window. Perhaps there's a way of telling Idea not to do this for certain file types or in code comments?</p>
