Managing Phrases 
The phrase manager is generally just another interface for doing translations. Data is just grouped by phrase instead of by language.

Clicking Languages & Phrases > Phrase Manager will lead you to a page that looks like this:

Phrases that are checked have a translation in that language; unchecked, empty circles are using the default value.

From here, you can add or edit and search for orphaned phrases.
