We can see all the translated items using Settings > Application Terms > Translated Terms.
But there is no dynamic translated values in the list. All are static values like labels. However, I made some queries in PostgreSQL and I found some translated values there.
Is there any UI to check and edit the translated field values in Odoo 10?
Usually the field itself has a little globe on the right upper corner in edit mode. For example in products:
Click to open the field's translations:
Another, and in my opinion better, way is using the module web_translate_dialog from OCA.
And that's it. You already found the menu with the list of records from model ir.translation which show every translation for the system. The little globe is opening it, too, but filters the correct field.
