* '''Element align''' - align the [[Contents|'''Contents''' window]] with the [[element window]] for convenient review of [[Glossary:Element|elements]] in the [[Contents|'''Contents''' window]] (note that '''Synchronize''' button must be down for the [[element window]] to be updated as the selection moves in the [[Contents|'''Contents''' window]])
