[texhax] The next to read after lshort?

[Steven Woody]

Hi,

I found lshort sometimes cannot answer my question.  For example, when
it talks about \newcommand, it even does not talk about how to use
optional arguments.  In this kind of situation, what is the right
documentation I should read?

Thanks in advance.
