Key localization?

[SayNooty]

Please tell me where to find the translation keys for localization of certain elements? I want to translate the description of an item into another language, but I don't know its translation key.

The descriptions of fields can be translated here: https://weblate.spyglassmc.com/projects/spyglass/vanilla-mcdoc/

Though note that currently these aren't used yet. Neither in spyglass nor on my website.
