ISO-639-3 language codes
Open Tools > ISO-639-3 Language Codes to look up the three-letter code used for a language. The window lists an ISO-639-3 code and Language Name for each bundled language entry.

Type in the field above the table to filter both columns. Filtering updates as you type and accepts a regular-expression pattern. Clear the field to show the full list again. If a pattern is not a valid regular expression, the current filter remains unchanged until the pattern is valid.
