Which is why I said elsewhere that without making the candidate scoring smarter, adding aliases based on namespaces will be much less useful, perhaps even detrimental. > What it should list is https://www.gnu.org/software/emacs/manual/html_node/elisp/Regexp-Search.html, but > also merged with the Match Data documentation, presented in a much more condensed manner, etc. The above are _commands_ not functions. The equivalent would be "C-h a regexp search RET", which does do what you want, I think.
