LaTeX Cheatsheet - LaTeX Academic Typesetting Reference
LaTeX rewards sticking to a few reliable snippets and punishes improvising at the last minute. Grouped by document structure, text formatting, math, lists, tables and references, each command shows its purpose and common companion packages. Use it to scaffold a paper skeleton, typeset math correctly, and wire up citations without re-opening the boring user guide. After reading you can draft an article that compiles on the first pass.

- Float placement [htbp]: h here, t top, b bottom, p separate page.
- Use \label and \ref for cross-references instead of hardcoding numbers.
