I see cite option under the questions. I want to know that what is the function of that cite button? Actually what is it for?
Any answer to this question is welcomed and will be appreciated by me.
In (La)TeX you can manage your references using BibTeX (see also here). The code displayed with the cite is the code you would insert into your BibTeX file to get the proper formatting when referencing a MSE post. It is also possible to the use amsrefs package with LaTeX, and you can have this code snippet displayed as well,
