Abbreviations and backslash

Abbreviations and backslash

[Hodei Usabiaga]

Hi everybody,

Is it possible to include a backslash in the abbreviation under emacs? e.g.
"\a" is replaced by "\alpha" 

I tried to introduce something like
(define-abbrev-table 'text-mode-abbrev-table '(
;abbreviations to long letters in the Greek alphabet
    ("\\a" "\\alpha" nil 0)
    ("\\b" "\\beta" nil 0)
))

in the abbreviation file, but the abbreviation doesn't work. It seems that
emacs do not accept any backslash character as an abbreviation. However, I
find those abbreviations very useful in order to write documents under
Latex. 

So, does anybody know how to include those kind of abbreviations in the
abbreviation list?

Note: the following lines were added in emacs file.  
(setq-default abbrev-mode t) 
;enable abbreviations
(setq save-abbrevs t)                                
;save abbreviations upon exiting emacs
(setq abbrev-file-name "~/abbreviations.el") 
;the file storing the abbreviations
(if (file-readable-p abbrev-file-name)                  
;read the abbreviations every
(read-abbrev-file abbrev-file-name)                   
;time emacs is started
)

The previous commands, the abbreviations commands included, seem to work
under Xemacs as shown in www.math.umn.edu/~aoleg/emacs/latex.shtml. 

Help, will be very much appreciated.

Thanks,

Hodei

This is not a direct help, but AUCTeX
<URL:http://www.gnu.org/software/auctex> has

C-c ~ runs the command LaTeX-math-mode
   which is an interactive compiled Lisp function in `latex.el'.
It is bound to C-c ~, <menu-bar> <LaTeX> <Math Mode>.
(LaTeX-math-mode &optional ARG)

A minor mode with easy access to TeX math macros.

Easy insertion of LaTeX math symbols.  If you give a prefix argument,
the symbols will be surrounded by dollar signs.  The following
commands are defined:
