# Citations

This vault has a `refs.bib` at its top level, so citations render.

Literate programming was introduced by [@knuth1984], and the argument for
showing data plainly comes from [@tufte2001]. Typst, the engine that typesets
math here, began as a thesis [@madje2022].

Your note keeps the plain text: what you typed is `[@knuth1984]`, and that is
exactly what is saved. Pandoc, Obsidian citation plugins, and .typ papers all
read the same file, so nothing here is wander-only.

Put your cursor inside a citation and it shows the key again, ready to edit.

A key that is not in refs.bib stays visible as written, with a dotted
underline, so a typo never turns into a silent wrong reference:
[@nosuchkey2099].

Citations inside code are left alone: `[@knuth1984]` stays literal.
