Abbreviation case-fixed

[J2129]

Hi,

I'm trying to have case-fixed abbreviations such that abbreviations which are defined as

("tst" "test" nil0)

don't expand unless I type in "tst" (not when I type in "Tst").  I would like to do this for every abbreviation in my abbreviation file. I understand that this is done using the case-fixed property, but I can't get this to work. Here is what I have as my abbrev.aab file:


(autoload 'expand-abbrev-hook "expand")

(define-abbrev-table 'global-abbrev-table  '(
    ("tst" "test" nil 0)
;;Many other abbreviations
)
:case-fixed t
)



Thanks!
Jeff
