I'm interested in adding more fractions similar to `C-x 8 1 / 2' and in adding another prefix for my commonly used emojis as `C-x 8 e ...' With a normal keymap I know I could do something like this: (global-set-key (kbd "C-x 8 1 / 5") (lambda () (interactive) (insert "⅕"))) (global-set-key (kbd "C-x 8 e c") (lambda () (interactive) (insert "✅"))) But C-x 8 uses iso-transl-ctl-x-8-map which is some kind of special translation map which I'm a bit vague about. Also there's some magic described in iso-transl.el about allowing Alt to work as well. The elisp manual doesn't mention C-x 8 stuff at all, and that seems to be by design based on bug #594. The emacs manual mentions how to use it but not how to extend it. I feel like customizing it should be described some place. -- Howard
