It is referred to as energybending on the Nick.com website, which, unfortunately, makes that the 'canonical' term. However, the creators and writers never named it or had a particular name in mind, as I understand it. And I still really don't like the term. There's a lot of useful supplementary information on the nick.com Avatar site...but one could argue that it's like the Expanded Universe books and information for Star Wars, a 'lesser' level of canon that doesn't originate from the original source.
Considering how weird Star Wars fans may get about interpretations and 'personal interpretations of canon' this might not be the best analogy, as nothing on the Nick.com website is contradictory to the flavor, style, or official canon of the show as a whole...but I'm going to reserve the right to be a silly fan and call 'Energybending' by a term I prefer.
Then that ruins my complete map with locations
