Subject: 25.0.94; isearch-toggle-character-fold keybinding missing
Date: Tue, 31 May 2016 09:06:14 -0400

According to the "Lax Search" Info page, isearch-toggle-character-fold
should be bound to `M-s '', but that does not appear to be the case.
The actual bindings I see, with `M-s C-h', are these:

    Global Bindings Starting With M-s:
    key             binding
    ---             -------

    M-s ESC		Prefix Command
    M-s .		isearch-forward-symbol-at-point
    M-s _		isearch-forward-symbol
    M-s h		Prefix Command
    M-s o		occur
    M-s w		isearch-forward-word

    M-s h .		highlight-symbol-at-point
    M-s h f		hi-lock-find-patterns
    M-s h l		highlight-lines-matching-regexp
    M-s h p		highlight-phrase
    M-s h r		highlight-regexp
    M-s h u		unhighlight-regexp
    M-s h w		hi-lock-write-interactive-patterns

    M-s M-w		eww-search-words

BTW, many thanks for the character-folding search feature.  I've wanted
that for a long time.

As for GNU Emacs 25.1.50.1, the function is called
‘isearch-toggle-char-fold’ (both in (info "(emacs) Lax Serach") and in
fact) and it is bound to ‘M-s '’ within isearch.  ‘Within’ means that
you have to invoke iserach first with ‘C-s’ or ‘C-M-s’ or somehow else.

However ‘M-s <f1>’ within incremetal search indeed returns help on
*global* bindings starting with M-s, not the bindings of iserach-mode,
so ‘M-s '’, ‘M-s e’ and others are missing in a help buffer.  I would
file this as a bug unless it is not filed already.

For what it’s worth, ‘which-key-mode’ acts correctly in this case.

Thanks, good to hear.

Is which-key-mode also 25.1 change?  I'm not familiar with it and get "No apropos matches for 'which-key-mode'" when I try to discover it.

In any case, I had first attempted 'M-s '' within search before invoking 'M-s C-h'.  I agree that it makes sense that the later should return help on the bindings of isearch-mode when invoked from it.

‘which-key-mode’ is not a part of GNU Emacs, you have to istall it from
melpa or melpa-stable (‘M-x package-install RET which-key’) first if
you’d like to use it.  I would recommend you to try.

      (which-key-mode 1)

It might be also useful sometimes to get a help for non-prefixed
keybindings, so you might like to map a spare help key sequence
(‘C-h C-k’ / ‘<f1> C-k’ for example):

   (define-key 'help-command (kbd "C-k") #'which-key-show-top-level)
