# Use of citation helper

New edit. I edited again the question following Martin Sleziak's comment below. As he correctly guessed, the question is not about the elementary use of the citation helper, so I found necessary to correct it. Apologies for my poor English.
Disclaimer. I believe this question is not a duplicate, since I have found only one pertaining to the same topic in Meta. However, if I am wrong, please tell me and I'll remove it immediately.

Recently I noticed the very useful "Citation Helper" on the toolbars of the edit sections of MathOverflow and of Mathematics.StackExchange. Does there exists a manual on how to use the tool inside a post? Precisely, I'd like very much to use cited items as tags, in a similar way as it already happens for numbered formulas in Math Jax. For example this formula $$\frac{\partial}{\partial t}f(t,\mathbf{x},\mathbf{v})+\mathbf{v}\cdot\nabla_\mathbf{x} f(t,\mathbf{x},\mathbf{v})+\mathbf{F}\cdot\nabla_\mathbf{v}f(t,\mathbf{x},\mathbf{v})=\mathsf{C}(f,\mathbf{x},\mathbf{v})\label{1}\tag{1}$$ is tagged and can be accessed by clicking on the hyperlink \eqref{1} whenever it is placed in the post. I would like to make items in a Bibliography or References section accessible from other part of my Qs&As by using hyperlinks placed in the main text: is this possible and, if so, where I can find the syntaxes for doing so?

• A nice explanation of how the citation helper works is in this blog post: MathOverflow and MathSciNet (Wayback Machine). Since then it has changed a bit - it now includes Zentralblatt link rather than MathSciNet. But that's not the substantial difference. I've seen this link in comments to this MathOverflow Meta post: New feature - citation helper. – Martin Sleziak Sep 7 '19 at 13:44
• However, it is quite likely that you're after something else. (As you write about "reference items ... using hyperlinks".) – Martin Sleziak Sep 7 '19 at 13:45
• Thanks for the updating the post (I am not sure, but perhaps after the edit the (hyperlinks tag might be also a suitable tag for the question.) If this feature request gets implemented at some point, I think that it could be used also for the purpose you describe: Support anchor names in posts. (Although I don't think it is very likely to happen, considering that the post has been around since 2010.) – Martin Sleziak Sep 7 '19 at 20:54
• I think if you had support for hyperref packages you could do this with mathjax. – user645636 Sep 8 '19 at 22:18
