The Info manual says in (info "(emacs) Menu Mouse Clicks")

  ‘C-mouse-2’
       This menu contains entries for examining faces and other text
       properties, and well as for setting them (the latter is mainly
       useful when editing enriched text; *note Enriched Text::).

But clicking C-mouse-2 signals the error:

  C-<mouse-2> is undefined

The above Info node has a link to the "Enriched Text" node
where (info "(emacs) Editing Format Info") says:

  The easiest way to alter properties is with the ‘Text Properties’ menu.
  You can get to this menu from the ‘Edit’ menu in the menu bar (*note
  Menu Bar::), or with ‘C-mouse-2’ (*note Menu Mouse Clicks::).

However, ‘C-mouse-2’ fails even in enriched-mode,
e.g. after visiting etc/enriched.txt.

Also the documented ‘Text Properties’ menu
is not displayed in enriched-mode.

PS: There is also this comment in lisp/mouse.el,
maybe it should be removed:

  ;; C-down-mouse-2 is bound in facemenu.el.

More fallout from removing facemenu load by default,
I guess.  (Why was that done, again?)

That's because that binding was removed as part of butchering
facemenu.el in Emacs 28.

I resurrected the C-mouse-2 binding, but it still needs facemenu to be
loaded before it will work.

Stefan, is there some way to make this auto-loaded?  That is, whenever
the user presses C-mouse-2, automatically load facemenu and show the
drop-down menu in facemenu-menu?  I tried autoloading the
facemenu-menu keymap like ispell and pcvs do, but that doesn't seem to
work, in the sense that pressing C-mouse-2 complains that the binding
is not a command.

The patch below works for me, should I push it?

Juri, is there anything else to be done here, or can we close this
bug?

What remains to do is this:

The documentation of the Enriched Mode in
(info "(emacs) Editing Format Info") says:

  The easiest way to alter properties is with the ‘Text Properties’ menu.
  You can get to this menu from the ‘Edit’ menu in the menu bar

But the documented ‘Text Properties’ menu is not displayed in enriched-mode.

This can be fixed by just requiring facemenu in enriched.el:
