That's hardly a clean solution.  A clean solution would avoid calling
Fx_popup_menu when it detects the situation we are talking about.

Yes, of course.  You can see that with "C-h l", for example.  Also,
every non-leaf menu item is a keymap.

If it turns out that mouse clicks can't be prefix keys, then the doc
should indeed be fixed.

Yeah, I'm having trouble going through it. Is there a way to make it
supported, though? For example, what about catching the error around
read_char_x_menu_prompt (keyboard.c:L2683) and not exiting if an error
was thrown? I'm not sure how to go about this in C.

Do you mean those mentioned in "(emacs) Menu Mouse Clicks"? Does
clicking in those menus count as key sequences?

If you are arguing that the manual is incomplete or inaccurate, I
could agree, but that's a different/separate issue, I'm sure.  Fixing
the docs is easy.

I just asked that question because my reading of the code is that this
is not supported.  Maybe I'm misreading: keyboard.c:read_char is not
for the faint at heart.

By making a menu, I presume.

Does the manual state that a mouse click can't be a prefix key? "(elisp)
Prefix Keys" states that "A prefix key is a key sequence whose binding
is a keymap", which mouse-3 as above satisfies:

(keymapp (key-binding [mouse-3])) =3D> t

As long as the mouse click isn't in some special area (mode-line,
menu-bar, etc.), then I would hope that it would be treated as a prefix
key.

Also, "(emacs) Mouse Buttons" states that "You can put more than one
mouse button in a key sequence, but it isn=E2=80=99t usual to do so.".

How would one do this if a mouse click can't be a prefix key? The
following also fails:

(define-prefix-command 'test)
(global-set-key (kbd "C-t") #'test)
(global-set-key (kbd "C-t <mouse-3> <mouse-2>") #'backward-word)

Eli, do you know how to solve this?

Try this:

(define-prefix-command 'test)
(global-set-key (kbd "C-t") #'test)
(global-set-key [mouse-3] #'test)
(global-set-key (kbd "C-t <mouse-2>") #'backward-word)
(global-set-key [mouse-3 mouse-2] #'backward-word)

Hitting C-t mouse-2 calls `backward-word' as intended, but hitting
mouse-3 mouse-2 displays an "Empty menu" error as in the original
report.

The error is thrown from Fx_popup_menu and is called from
read_char_x_menu_prompt, which is only called in the mouse case. I'm not
sure how to proceed from here.

This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your report will be posted to the bug-gnu-emacs@HIDDEN mailing list
and the gnu.emacs.bug news group, and at http://debbugs.gnu.org.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug.  If you can, give
a recipe starting from `emacs -Q':

The manual states at the end of Section 48.3.10 "Rebinding Mouse Buttons"
says "You can put more than one mouse button in a key sequence, but it
isn't usual to do so."

I failed to bind a simple function to a sequence of two mouse keys.

> emacs -Q

inside the *scratch* buffer, evaluate:

(defun go-backwards ()
            "Go backward one word."
            (interactive)
            (backward-word 1))
(global-unset-key [mouse-3])
(global-set-key [mouse-3 mouse-2] 'go-backwards)

Now, pressing the right mouse button gives the message

Empty menu

at the bottom of the Emacs screen.

If I evaluate

(setq debug-on-error t)

and press the right button again I get just

Debugger entered--Lisp error: (error "Empty menu")

However, after evaluating

(global-set-key [mouse-3] 'go-backwards)

pressing the right mouse button does indeed move the point backward one
word; therefore binding a single mouse key works.

Another way to obtain the same result is the following.

Evaluate

(defun go-backwards ()
            "Go backward one word."
            (interactive)
            (backward-word 1))
(global-unset-key [mouse-3])
(defvar my-map (make-sparse-keymap))
(define-key my-map [mouse-2] 'go-backwards)

Now, C-h v my-map gives clearly

my-map's value is (keymap
 (mouse-2 . go-backwards))

Then evaluating

(define-key global-map [mouse-3] my-map)

gives

(keymap (mouse-2 . go-backwards))

at the bottom of the Emacs screen. However, again the right button gives
"Empty menu".
