Library `mouse3.el' gives you a context-sensitive menu
on `mouse-3'.  And yet it still also gives you the
normal Emacs `mouse-3' behavior.

You or your code can customize what the menu shows in
different contexts.

I'm guessing you mean functions (in particular,
commands) that are new to you, and not necessarily
new to Emacs.

Icicles can help with discoverability in a few ways:

 * See what you can do at any moment:
   . See which possible inputs are expected by a
     command that reads input
   . See which key sequences are currently available,
     which of them are general vs which are local,
     and what each of them does
 * See individual descriptions of the possible inputs,
   that is, help on completion candidates
 * Find menu items more easily
 * Find commands more easily
 * Find help in the doc
 * Learn how to use regexps

Menus in general, and La Carte in particular, can also
help with discoverability, and even more so when combined
with substring or regexp completion (e.g. Icicles).

Hmm, I’ll take a look at that :-)
Is Mouse-3 the right-click button in usual mice?

Looking at the link, Icicles is a package similar to which-key, am I right?

I am impressed with this; I should implement something similar with helm when I have free-time :-)

Yes.

Regarding help by showing keys currently available, yes.
Not the same in that regard, but similar, yes.

In other ways it is similar to Helm or Ivy (rather, they
are similar to it).  It is what is sometimes called, now,
a completion framework.

The help on keys works by completing keys ("completion"
can also start from an empty key sequence).
