In the GTK version of emacs, the keybinding notes for the "Edit > Cut"
and "Edit > Copy" menu entries say "<cut>" and "<copy>" respectively.
Those names don't seem very useful to me, as most keyboards don't have
such keys; also they don't help teach the real Emacs bindings.
Shouldn't those just say "C-w" and "M-w" ?

There is the same problem on w32 (which we discussed long ago).

This happens to come up periodically; I remember at least 2
discussions in the past. <cut> and <copy> are Sun keyboard's keys,
and IIRC the problem is we don't have any good way to specify, for a
command that has several keybindings, which one gets mentioned in the
menu. I think we currently display the last one bound.
Also, please note that, at least by default on GUI displays, these
menu items don't invoke the same functions as C-w and M-w (because
x-win.el turns on menu-bar-enable-clipboard).

Would it help if they invoked the same functions? Could we not fix that?

??? They invoke different functions for a reason, please see the
source of the respective functions on menu-bar.el. In other words,
this is a deliberate feature. Are you suggesting to turn it off?

I guess he'd rather use the same function which discriminates by some
other means between the two uses.
Alternatively, one could put explicit keyboard help strings into the
menus (or have some property for that purpose on the function?). One
might assume that the people with actual "<cut>", "<paste>", "<copy>"
keys would still try using them without being prompted for them.

Yes, this is a general problem with `substitute-command-keys', which we have
discussed before. Whenever there is more than one key sequence bound to a
command, the problem surfaces.
No matter what algorithm is used to choose (ASCII, non-ASCII, shortest,
longest, chords, non-chords, whatever), people will want to be able to
specify the binding to use in the result, and there is no way to do that
now. I hope we will address this after the release and find a good solution.
In my own libraries I sometimes hard-code explicit bindings and sometimes
rely upon \\[...]. The advantage of the former is that you can control what
gets communicated; the disadvantage is that that can be incorrect if the
user has changed the bindings.

In some pars of Emacs we use another trick: make and use an alias, like
`advertised-undo'. I think this is a bad solution because C-h f undo RET
then lists all bindings except for the "advertised" one C-x u.
Maybe a better solution is to add a `advertised-binding' property to the
function's symbol:
(put 'undo 'advertised-binding [?\C-x ?u])
which could be used similarly to the :key-sequence property in menus
(i.e. it's used if the key seuqnece is indeed bound to the specified
command).

I agree.

(put 'undo 'advertised-binding [?\C-x ?u])
which could be used similarly to the :key-sequence property in menus
(i.e. it's used if the key seuqnece is indeed bound to the specified
command).
Some other ideas were kicked around previously. I don't recall them, but
it's worth discussing all of them sometime after the release. I like your
idea, but:
- What to do if the key sequence is not bound to the specified command and
there are several bindings? Which to pick?
- It might increase maintenance (but so might other solutions): Changing the
bindings in the library would also mean updating this property.
One question to consider is whether we want to allow control over what gets
communicated 1) at the point of use of `substitute-command-keys' or a doc
string or 2) at some earlier, more general point - or both.
For #2, a library might (somehow, perhaps using more or less the mechanism
you proposed) specify a list of bindings, in preference order, that would
apply to all uses of `substitute-command-keys' and all doc strings.
For #1, we might devise some way to indicate the preferred binding to use at
the point of call. For example (just thinking out loud; not a proposal),
"\\[((kbd "C-x") (kbd <f1> SPC) (kbd "C-M-<down>"))...]" might stipulate
using binding (kbd "C-x") if applicable, else (kbd <f1> SPC) if applicable,
else (kbd "C-M-<down>"). There might also be some way to specify a default
for the case where none were applicable.
Both general presciption (#2) and spec at point of use (#1) could of course
be used together, the latter (#1) taking precedence.

It is a good idea, but let's not consider it until after the release.

The usual solution is to create an alias, such as advertised-undo.

Yes, thanks, that is of course what I suggested. Are there any
advantages not to do it the way I suggested?
