I know that I can use
(abbrev-table-put c++-mode-abbrev-table :case-fixed t)
to make one abbrev table to be case sensitive. But how can I make this default for all abbrev-tables ?
(dolist (table abbrev-table-name-list) (abbrev-table-put (symbol-value table) :case-fixed t)) C-x a i g are created using all lowercase for the unexpanded value.
