\leftgroup{} \rightgroup{} - groups of fence delimiters, for example \leftgroup{[} is equivalent to \left[

\overset{}{} - groups of embellishments set above, for example \overset{-}{a} is equivalent to \overline a

\underset{}{} - groups of embellishments set below, for example \underset{-}{a} is equivalent to \underline a

{} \overgroup{}{} - groups of horizontal division style delimiters, for example {a} \overgroup{-} {b} is equivalent to a \over b

\unicode{c-style-hex-string} - the unicode character refered to by hex-string

\begin{array} \end{array}

&

\\ recognized as an array delimiter, but comments are not supported

\mathrm{}

\, \: \; negative spaces are neither recognized nor implemented

\left[{( \right]})

\sqrt{}

\over

superscripts and subscripts

upper and lower case greek alphabet

named functions

embellishments both narrow and wide and underline

all the symbols I know about except those listed below

\frac

\root[]{}

\begin{math} \begin{display} \begin{equation} and the corresponding \end and the abbreviations \( \[
