title: Support Table
---
This is a list of TeX functions, sorted alphabetically. This list includes functions that KaTeX supports and some that it doesn't support. There is a similar page, with functions [sorted by type](supported.md).

If you know the shape of a character, but not its name, [Detexify](https://detexify.kirelabs.org/classify.html) can help.
