However, `C-x a C-x C-h' reveals > that there are no commands bound to anything beginning with that > prefix. Why? Good question. I wonder too. Same thing in Emacs 22, 21, and 20. And C-x C-x C-x C-x C-x ... just keeps on keepin on. `C-x a' is bound to `abbrev-map', but its value is this: (keymap (110 . expand-jump-to-next-slot) (112 . expand-jump-to-previous-slot) (39 . expand-abbrev) (101 . expand-abbrev) (45 . inverse-add-global-abbrev) (105 keymap (108 . inverse-add-mode-abbrev) (103 . inverse-add-global-abbrev)) (43 . add-mode-abbrev) (103 . add-global-abbrev) (1 . add-mode-abbrev) (108 . add-mode-abbrev)) No entry for C-x, that I can see. And in English: key binding --- ------- C-a add-mode-abbrev ' expand-abbrev + add-mode-abbrev - inverse-add-global-abbrev e expand-abbrev g add-global-abbrev i Prefix Command l add-mode-abbrev n expand-jump-to-next-slot p expand-jump-to-previous-slot i g inverse-add-global-abbrev i l inverse-add-mode-abbrev I don't see anything that would explain this in the Lisp sources, grepping for `abbrev-map'. I'm curious what the answer will be.
