The way to reproduce:
emacs -Q
ESC <f10>
Emacs says that it is undefined, but it should be defined:
toggle-frame-maximized is an interactive compiled Lisp function in
`frame.el'.
It is bound to <M-f10>.

But Emacs doesn't think that ESC <f10> is <M-f10>:
ESC <f10> (translated from <escape> <f10>) is undefined
Which AFAIU is the root cause of the problem, or maybe a feature.

Why? In:
(info "(emacs) User Input")
(info "(emacs) Misc Help")
(info "(emacs) Spelling")
and so many nodes in Emacs manuals, <ESC> is described the same as <meta> (except that it is entered as a separate character.)

bindings.el has this interesting section:
;;; These are dangerous in various situations,
;;; so let's not encourage anyone to use them.
;;;(define-key global-map [C-M-delete] 'backward-kill-sexp)
;;;(define-key global-map [C-M-backspace] 'backward-kill-sexp)
(define-key esc-map [C-delete] 'backward-kill-sexp)
(define-key esc-map [C-backspace] 'backward-kill-sexp)
So it looks like a feature that [M-foo] and ESC [foo] are separate. All
other places where [M-foo] are bound explicitly bind ESC [foo] as well.
Andreas.

In (info "(elisp) Format of Keymaps"):
Keymaps do not directly record bindings for the meta characters.
Instead, meta characters are regarded for purposes of key lookup as
sequences of two characters, the first of which is <ESC> (or whatever
is currently the value of `meta-prefix-char'). Thus, the key `M-a' is
internally represented as `<ESC> a', and its global binding is found at
the slot for `a' in `esc-map' (*note Prefix Keys::).
So is there a bug in the GNU Emacs Lisp manual?

Sorry, I ignored the next paragraph, which is:
This conversion applies only to characters, not to function keys or
other input events; thus, `M-<end>' has nothing to do with `<ESC>
<end>'.

It is intended to mimic the Gnome key <M-f10> that has
no ESC <f10> equivalent. But maybe we should also bind ESC <f10>
to allow the users to use it as an Emacs alternative
to the system key <M-f10> when it is taken by Gnome
(both should do the same but there are still some bugs that
prevent the correct processing of the system key on non-GTK builds).
