Question about which-key. Can which-key be used to let me know what key chords are available while in an interactive command in the mini-buffer?

EDIT: I meant key sequences or key bindings for the title. (Key chords are those which are pressed simultaneously ala the key-chord package.) For example, I'm editing a file and press `C-s` to enter an iSearch. The minibuffer presents "I-search:". At that point, I'd like to know which key chord combinations are available. I imagine, if this is even possible, I would need to bind my own key chord to a which-key command, something like this: (global-set-key (kbd "C-M-\`") #'which-key-show-top-level) But that only shows the top level commands (for the current major mode?). Or perhaps there's another package that does this? Note: I'd like to have a generalized solution, not necessarily just for iSearch.

I'll answer my own question! After pressing `C-s`, if you're stuck, press `C-h`. At that point, which-key will offer you many options, some of which start with "isearch-". From there, you can see the following options can help you out: b -> isearch-describe-bindings m -> isearch-describe-mode

1. If you use Emacs 28, or you use library [`help-fns.el`](https://www.emacswiki.org/emacs/download/help-fns%2b.el) (any Emacs release) then you can use `M-x describe-keymap` (bound to `C-h M-k` in `help-fns.el`) to show the bindings in `isearch-mode-map`. 2. If you use library [Key See](https://www.emacswiki.org/emacs/KeySee) ([`keysee.el`](https://www.emacswiki.org/emacs/download/keysee.el)) then you can complete keys at any level, including while isearching. You can, for example, drill down into the `M-s` prefix-key bindings for Isearch. You can sort the bindings by prefix keys first, local keys first, or command name (alphabetically). (Completion candidates include both key and command.)

Thanks, that was very helpful! One question. I don't see help-fns.el on github, but I do see this: https://github.com/emacsmirror/help-fns-plus. Is help-fns-plus a branch of help-fns, extending it? Can I just go with that? Or is help-fns-plus an additional file to use along with help-fns?

* `help-fns.el` is a standard library, delivered as *part of Emacs*. You don't need to download it - it's already in your Emacs. * [`help-fns+.el`](https://www.emacswiki.org/emacs/download/help-fns%2b.el) (note the `+` char) is an external library that enhances what the standard library does. I've given you the direct link to the download of the latter library from the Emacs Wiki [ElispArea](https://www.emacswiki.org/emacs/ElispArea) (both here and in my last msg). This (not what you've shown) is the correct link to `help-fns+.el` on the EmacsWiki GitHub mirror: https://github.com/emacsmirror/help-fns-plus/blob/master/help-fns%2B.el. However, if you want to be sure to get the latest version of the library then use the Emacs Wiki link. After you've downloaded `help-fns+.el`, put it in a directory that's in your `load-path`, and put `(require 'help-fns+)` in your init file.

Thank you so much! I clearly had some missing puzzle pieces in my brain, and that added another few pieces!
