Frequently Asked Question List for TeX


Contributing to the FAQ

Thanks for considering contributing to the TeX FAQ: feedback, fixes and ideas are all useful.

ChangeLog, commit messages and authors

Please note any significant change to the content of questions in, including which question is changed in the format Q-<name>.

Commit messages where the content of a single question is changed should start with Q-<name>. Changes to the content of questions should always be made in separate commits: formatting, typos or other ‘non-significant’ changes can be made for multiple questions in one go. When you change the content of an answer, please update the date line at the bottom of the page.

If you are making a significant change to the content, please make sure you add yourself to the contributors list.

Categories and tags

Every question in the FAQ should belong to exactly one category: this is specified in the YAML header of the source, for example

title: What's wrong with `\bf`, `\it`, etc.?
category: usage
permalink: /FAQ-2letterfontcmd
date: 2014-06-10

The aim of the categories is to be relative broad-brush such that the total number remains manageable. The current set of categories is used to auto-generate the main index: this should be consulted when creating new questions (or proposing revision of the categories).

Questions may also have one or more tags, again specified in the YAML, for example:

title: Master and slave counters
category: programming
  - latex
  - macros
permalink: /FAQ-addtoreset
date: 2014-06-10

At present, the total number of tags is small, and not all questions are tagged. Unlike categories, questions may have no tags or multiple tags, and the set of tags is expected to grow over time. The current set of tags are listed in the questions-by-tag page.


The online TeX FAQ is written in GitHub-flavoured Markdown, and uses the GitHub Pages system to convert this to web pages. In general, Markdown is easy to use, and offers enough formatting power to make the FAQ useful. There are a few things to watch out for
