Mode independent abbrev tables

[Andreas Röhler]

Hi,

is there a way to load specific abbrev-tables without regard of the 
current major-mode?

Tried

(define-minor-mode ar-math-insert-mode
  "Convenient enter mathematical characters."
  nil " aMI"
  (setq local-abbrev-table ar-math-insert-mode-abbrev-table)
  )

but doesn't work.

Thanks,
Andreas
