I wanted to write the \underbar in the [mathexchange site][1], but it wasn't possible when using \underbar{}. Is it possible to define my own commands for the math exchange site or how do I get access to all the available symbols for the site?

I'm not interested in debating to add features, I just want

  1. to use the command I want to use


  1. know a reference of all the available commands for future reference.

LaTeX support on this site is provided by MathJaX.

MathJaX documentation has a long list of Supported LaTeX commands. Note that some of them are provided by extensions, as indicated on the list -- those extensions are not enabled here.
