title: Support Table
source: https://raw.githubusercontent.com/KaTeX/KaTeX/master/docs/support_table.md

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.

If you know the shape of a character, but not its name, Detexify can help.
