# \synctex

Den `\synctex` primitiv er en tilføjelse til TEX, som leveres af [SyncTEX-udvidelsen](https://ctan.org/tex-archive/support/synctex-parser?lang=en). SyncTEX kan aktiveres eller deaktiveres via en kommandolinjeindstilling til en TEX-motor eller direkte i en TEX-kildefil via `\synctex` primitiv:

**Brugseksempler**

* for at aktivere SyncTEX, brug `\synctex=1` i dine `.tex` fil;
* for at deaktivere SyncTEX, brug `\synctex=0` i dine `.tex` fil;

Jeg citerer denne beskrivelse fra [CTAN](https://ctan.org/tex-archive/support/synctex-parser?lang=en):

> Synkroniseringsteknologi, kaldet SyncTEX, er en funktion i TEX-motorer. Den muliggør synkronisering mellem input og output, hvilket betyder, at man kan navigere fra kildedokumentet til det typograferede materiale og omvendt. Sådan fungerer det: under typograferingen af `foo.tex`, skriver TEX-motorerne nogle geometriske oplysninger i en hjælpefil ved navn `foo.synctex`, bruges disse oplysninger derefter af redigeringsprogrammer eller fremvisere til at navigere mellem input og output.

SyncTEX understøttes af Overleaf.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://overleaf-pro.ayaka.space/latex/da/tex-latex-primitiver/12-synctex.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
