Subject: bug#59130: Inconsistent behaviour with key-translation-map
Date: Tue, 8 Nov 2022 20:37:36 +0100

It's possible to remap keys into other keys or sequence of keys via
key-translation-map
(https://www.gnu.org/software/emacs/manual/html_node/elisp/Translation-Keymaps.html).

For example,

setting
(define-key key-translation-map (kbd "<apps>") (kbd "C-x C-f"))
and pressing <apps> will execute command find-file,

setting
(define-key key-translation-map (kbd "<apps>") (kbd "C-x"))
and pressing <apps> C-f will execute command find-file.

However, setting
(define-key key-translation-map (kbd "<apps>") (kbd "C-x @ h"))
and pressing <apps> p will not execute H-p.

(C-x @ h adds prefix hyper
https://www.gnu.org/software/emacs/manual/html_node/emacs/Modifier-Keys.html)

Is this an issue or as expected?
