Tags
A tag is a keyword or label that categorizes your question with other, similar questions.
TikZ is a higher-level drawing language built on top of the PGF graphics framework. For questions specifically about the PGF layer use {pgf-core} instead. Both tags are possible on the same question. The tag {diagrams} is also compatible with this tag.
34745 questions

17910 questions
{beamer} is a document class for creating presentations and slides. For general questions about presentations or slides, independent of the document class, use {presentations} tag instead.
11439 questions
{math-mode} is about typesetting mathematical content, e.g. tweaking the appearance of spacing and symbols in a formula, or producing specific mathematical constructs. For questions about "wrapper" environments like equation or align, consider the tag {equations}.
9697 questions

5758 questions
XeTeX is a Unicode-capable variant of the TeX engine. Use this tag if your question is about Xe(La)TeX specific problems and is not related to standard (La)TeX.
5639 questions
{horizontal-alignment} is about aligning document elements horizontally, e.g. typesetting paragraphs using \centering or \raggedright or adjusting the horizontal position of several equation or table components.
If your question is generally about (horizontal) white space, use {spacing} instead.
