How to find commands run by menu?

How to find commands run by menu?

[kj]

Is there any way to determine the exact command that gets run when
one invokes a particular menu item?

TIA!

kynnjo

P.S.  Here's why I want this.  It's a bit convoluted.  For mysterious
reasons, the latest version of Emacs on my system does not offer
any "print region" commands when run in X11 mode (these commands
do show in the File menu, but are permanently disabled, irrespective
of whether a region is defined or not).

I determined that if instead I run Emacs in text mode, now the
menus do offer the "print region" commands.

But I don't want to run Emacs in text mode.  Therefore, I want to
be able to execute *while on X11 mode* the same commands that get
triggered when I choose (in text mode) one of the "print region"
commands from the File menu.  Make sense?

I thought that the desired commands would be ones like ps-print-region,
but the ones I've guessed produce different-looking printed results
from those obtained by using the menus under text mode, and I prefer
the latter by far.  Therefore, I have to conclude that using the
menus does something more than just calling, say, ps-print-region.

Yes.  You do that with C-h k and select the command in the menu.

Notice also that if you get the documentation of a command that is
accessible from a menu, this is signaled as "It is bound to ...".

I can't figure out how to do this when I'm in text mode.  In text
mode, to select the command I want from the menu (File > Postscript
Print Region (B+W)), the entire keystroke sequence is M-` f 3.  If
I prefix this sequence with C-h k, then the info command responds
with:

  M-` runs the command tmm-menubar, which is an interactive compiled
  Lisp function in `tmm.el'.

  It is bound to M-`.

  (tmm-menubar &optional X-POSITION)

  Text-mode emulation of looking and choosing from a menubar.
  See the documentation for `tmm-prompt'.
  X-POSITION, if non-nil, specifies a horizontal position within the menu bar;
  we make that menu bar item (the one at that position) the default choice.

So I never get to the point of querying the meaning of the last
keystroke of the sequence (3).

I also tried to hit C-h k after having hit M-` f but before hitting
3.  In this case the info message is

  3 runs the command tmm-shortcut, which is an interactive compiled Lisp
  function in `tmm.el'.

  It is bound to many ordinary text characters.

  (tmm-shortcut)

  Choose the shortcut that the user typed.


...which is not what I'm looking for.

Well, then you will have to see what's put in the menu.  I don't know
how this is done, but using apropos, or scanning the sources, you may
find either functions to get the menus and menu items, and see what
function is associated with what menu, or you may find in the sources
where the menus are created what function is associated.

Did you think of creating the region first? When nothing is marked,  
why should an obviously useless command, which only works on marked  
regions, be displayed?

Hi,

seems no easy way to solve your question. Which is an
inconvenience AFAIS. For the moment here a possible
proceeding relying at the tooltip shown:

From to the source-code directory,

with M-x grep-find and the command

find . -type f -name "*.el" -print0 | xargs -0 -e grep -nH -e "Print region between mark"

it displays

./lisp/menu-bar.el:125:	      :help ,(purecopy "Print region between mark and current position")))

with RET at the link the source is shown:

(define-key menu-bar-file-menu [print-region]
  `(menu-item ,(purecopy "Print Region") print-region
	      :enable mark-active
	      :help ,(purecopy "Print region between mark and current position")))

From there I guess "print-region" is the command looked for...

HTH

I think that it actually calls ps-print-region-with-faces

C-h k, then place the mouse on the appropriate menu item.

When I do C-h k, then work my way down to the 'Postscript Print Buffer'
item, and release the mouse button, emacs tells me that the function is
(ps-print-buffer-with-faces)

I suspect you are being affected by bug#4122:

http://emacsbugs.donarmstrong.com/cgi-bin/bugreport.cgi?bug=4122

See the workaround posted there, or use the 23.2 pretest where this
should be fixed.

[kj]

Many thanks for all your help.  (As usual, I end up learning a lot
more useful stuff from your answers than what my original question
required!)

Indeed, the commands I was looking for are

print-region
ps-print-region-with-faces
ps-print-region

Cheers,
