Lists all Base Text that is unknown to the [link:http://www.javapractices.com/apps/web4j/javadoc/hirondelle/web4j/ui/translate/Translator.html Translator] (more precisely, the in-memory version of the Translator). This screen is especially useful during development, since it allows the Base Text to be gathered *simply by exercising the application*. The general steps are :| ~ develop a feature as if the application has only a single language. ~ during final unit testing of the feature, re-start the application and exercise it to ensure all possible textual variations are emitted, including all error messages. ~ at this stage, all text intended for translation will be found and "recorded" in memory as "unknown base text". ~ hit the "Stop" button on this page to stop the "recording" of unknown base text. This will persist the unknown items into the database. ~ view the listing on this screen and decide what to do with each item : ignore it, treat is as a coder key, or as a natural language key. (The actual translation of such keys into other languages is performed later.) ~ _when the listing is emptied_, you have the option of repeating the process, by hitting the "Start" button on this page.
