It's even nearer at hand:
C-h i g "(Emacs)Regexps" or `(Elisp)Regular Expressions'

While we are at it: Is there an accepted quoting style for arguments
etc.?  For example:

1. In the above case expressing the need for pressing keys and
   distinguishing between textual arguments for the minibuffer: "" or
   `' or something else?

2. In the comment string of functions when expressing also key
   bindings and subsequent command names: "Please type `M-x
   function-name'" or "Please type \"M-x function-name\""?

I can't remember there is something in the Elisp manual for coding
conventions.
