## Context

  I am using Mathematica to create live documents -- documents that are both interactive and show mathematical derivations.

  Now, I'm aware that there are certain symbols that are available via:

    \[CapitaSigma]
  or
    <esc>S</esc>

  However, some of the symbols I want (\in, \subsetneq) do not belong in the greek letters. Is there a list of something similar to http://www.tex.ac.uk/tex-archive/info/symbols/comprehensive/symbols-a4.pdf
  but lists Mathematica symbols instead of LaTeX symbols?

Thanks!
