<sup>Originally posted by **jordan-melendez** September 12, 2022</sup>
In certain journals it is common to format references to equations like `Eq. (1.1)` with parentheses around the equation number. Quarto supports modifying `Eq.` with `eq-prefix`, but would it be possible to either

1. Add a parameter similar to `eq-prefix` that allows one to customize the reference further, and/or
2. Ensure that, when compiled to PDF, `\eqref` gets used rather than `\ref` for equation references. This would require `amsmath` I suppose, but would automatically add parentheses and permit further customization.

Thanks!</div>
