# Getting emacs to convert latex on the fly?

What's really nice about posting in the math stackexchange, and other forums, is that you can view the latex symbols right below as you're typing your post. Is there a way to do this in emacs? That is, can I type "$\in$" and have it immediately convert the code to the "element of" symbol (in the position where I typed it)?

1. you can also use x-symbol which uses fonts to display $\int$ as an integral. Again it works in ANY buffer. I am not sure that x-symbol still works with recent GNU emacs 24 but I do know it works for Xemacs.
