I added some text in https://docs.moodle.org/402/en/Translation_FAQ#Strings_named_.2A_link . Please feel free to add/remove/change as needed.
There are 445 strings named *_link!
But very few are real strings that must be translated. eg:
login_behaviour_link_selector | auth_unilogin 'Link insertion selector'
These few are worth translating, but I think I should better leave the others in English !
