How do I abbreviate Fig. and Eqn. in Quarto crossreferences?

Description

The journals in my area of study haven't published quarto templates yet. In the meantime, how can I get the cross-references to abbreviate to Fig. and Eqn.?

Use:

---
language:
  crossref-fig-title: Fig
---

See https://quarto.org/docs/authoring/language.html#alternate-language.

EDIT: directly using crossref key as mentioned by @cderv (#7000 (comment))

---
crossref:
  fig-title: Fig
---

See https://quarto.org/docs/authoring/cross-references.html#options.

Using language is probably working too, but I believe the right way to do that is tweaking the crossref option directly
https://quarto.org/docs/authoring/cross-references.html#options

Especially with new crossref system in next 1.4 version, the crossref key should be the one to target

By the way, is possible to localised a custom cross-ref? (cc @cscheid)

Good question. You are supposed to supply "Video", "Diagram", etc, and so you can provide the localized versions of those directly. But there currently isn't a direct way to do it in multi-language setups. We can leverage project profile metadata for it, but it might be a good idea to do this correctly. Let's discuss this in a meeting.
