Translated terms are stored in the database table for the ir.translation model. The Technical Translation option in the Debug menu provides quick access to those terms, in context with the currently selected view.

Similarly, model fields with translatable content will feature an icon to access the list of the installed languages and to set the appropriate value for each language.

Alternatively, the translation terms can be accessed from the Settings top menu using the Translations|Application Terms|Translated Terms menu option. Here, we can see all the terms that are available for our instance. We should use data filters to locate the terms we might be interested in.
