Is there any way of getting org-mode to display inline LaTeX fragments in the emacs buffer? E.g. I would like to be able to type:
The size of the hypotenuse is $\sqrt{a^2+b^2}$
and then the buffer immediately shows:
The size of the hypotenuse is √a²+b²
where √a²+b² is a png image rendered via dvipng.
I assume a toggle would switch between either seeing the formula or seeing the source of the formula, just like for the display of inline images. Also, pressing a backspace when the cursor is at the end of the formula should erase the trailing $ sign, and turn off image display of the formula, just like for [[links][name]].
