Latex symbols in GNU Emacs

[Ritchie <ritchiecai@gmail.com>]

For those of you who are using GNU Emacs as the text editor for
editing latex documents, I'm wondering is there a way to display all
the latex symbols?

I'm using Carbon Emacs on mac. When editing latex files, there is a
latex-math-mode available. With that mode enabled, there is an extra
drop down menu for all the latex symbols, but all the symbols are
listed as actual command name. I'm wondering if there is a way to
display some kind of picture of how each symbols may look like, and
you can choose them by clicking them.

There is a similar feature in xemacs provided by latex-symbols
package, but that package is for xemacs only. I tried x-symbols
package for emacs, but it doesn't seems to be able to do that either.
