> Using an anonymous function to translate keys as described in the Elisp manual at http://www.gnu.org/software/emacs/manual/html_node/elisp/Translation-Keymaps.html does not work as expected.
> Using a named function to map C-e to C-c, the Key Translation is successful:
> (progn (fset 'foo (lambda (prompt) (kbd "C-c")))
> (define-key key-translation-map (kbd "C-e") 'foo))
> Using an anonymous function for another keymap binds C-e to the lambda-defined command.
> (define-key global-map
> (kbd "C-e")
> (lambda () (interactive) (message "Inside C-e's lambda")))
> But using an anonymous function for key-translation-map does not change behavior of inputting C-e:
> (define-key key-translation-map
> (kbd "C-e")
> (lambda (prompt) (kbd "C-c")))
> I find no reason why the last Elisp shouldn't define a Key Translation. The Elisp manual section on Anonymous Functions states "Anonymous functions are valid wherever function names are." ( http://www.gnu.org/software/emacs/manual/html_node/elisp/Anonymous-Functions.html )
I found where the definition of a key translation is called, and made a patch. The quoted test case works correctly now. Is the change ok?
