Before the recent binding of C-h C-h to help-for-help, C-h C-h was unbound and thus used the default behavior of printing help for all keys bound to the prefix map. As an example see the behavior for C-x C-h. If the user bound a key with C-h prefix, that binding previously would show up in C-h C-h help. Example: User binds C-h M Before help-for-help was introduced: C-h C-h would display the user-bound C-h M mapping After help-for-help was introduced: C-h C-h does not display any user mappings with C-h prefix See https://www.gnu.org/software/emacs/manual/html_node/emacs/Keys.html Typing the help character (C-h or F1) after a prefix key displays a list of the commands starting with that prefix. The sole exception to this rule is ESC: ESC C-h is equivalent to C-M-h, which does something else entirely. You can, however, use F1 to display a list of commands starting with ESC.
