iTeX has undergone a few updates recently. Highlights include:

1. A proper LaTeX-like array environment,
2. Extensible arrows with optional arguments.

As always, the full list of commands is available from Jacques Distler’s website

\begin{array}[t]{clrc}
1 & 2 & 3 & 4 \\
5 & 6 & 7 & 8 \\
9 & 10& 11& 12
\end{array}

what is [t]? The whole syntax without t-part is the usual one I use, but t ??

The optional argument (which is also in LaTeX) specifies how the array will be aligned with the surrounding text. A ’t’ designates that the top of the array should be aligned with the surrounding text, ’b’ the bottom, and ’c’ the centre (also the default, ie what happens if you leave out the optional argument).

(Note: I haven’t updated the itex on the forum yet so this won’t work here)
