Re: sexps in tex modes

[Joe Corneli <jcorneli@math.utexas.edu>]

Here is another example,

  X\rightarrow

In mail-mode this is two sexps, but in latex-mode it is only one.
Since "X\rightarrow Y" contains three mathematical atoms, it should
be three sexps. 

Contrary to what I said before, in math mode, "abc" would typically
be properly understood as the product of three variables, so perhaps
it should actually be three sexps, though inside of an appropriate
markup instruction, like "\text{abc}", it would be only one sexp.

I agree that this is complicated -- any advice about how to approach
these sorts of problems would be appreciated.



   In LaTeX mode I think this should be two sexps:

   =abc

   Currently it is just one.  I'd like to know how to fix this!
