bookmark+ keybinding question

bookmark+ keybinding question

[Christopher Howard]

Hi Drew, could you give me a little guidance on something: I'm wanting, while viewing the bookmark list, to unbind "\M-o" from the bmkp-bmenu-w32-jump-to-marked, because I have a global M-o binding that I use very frequently, and this is causing me some inconvenience. I was thinking I could do something like this in my init.el:

```
(add-hook ???
          (lambda ()
            (unbind-key "\M-o")))
```

But I can't seem to figure out the correct hook. I'd rather not edit the bookmark+ code itself if I can avoid that.

The first step is finding out what keymap to use.
In this case, it's `bookmark-bmenu-mode-map'.

This is the traditional way to remove a key binding:
bind the key to nil in the particular map.

(define-key bookmark-bmenu-mode-map "\M-o" nil)

(In recent Emacs versions there are also `unbind-key'
and `keymap-unset'.)

Thank you. Is there an automated way to figure out what the correct keymap is? I find that C-h k does not provide any information regarding that.

Not really, that I'm aware of.  But often it's a
map for the current major mode, and in that case
its name is conventionally similar.  (But there
are also minor modes, with their own maps.)

`C-h v major-mode' gives you the name of the major
mode.  For the bookmark-list display that's
`bookmark-bmenu-mode'.  And its main keymap is ...
`bookmark-bmenu-mode-map'.

`M-x describe-keymap' shows you all of the bindings
in a given keymap.

I say "main keymap" because there can be others.
For example, the menu-bar menus for mode
`bookmark-bmenu-mode' are on keymap
`bmkp-bmenu-menubar-menu'.  (Menu keymaps often
end in `-menu' - they don't even contain the word
"keymap".)

As always, the source code is your friend.  There
you find keymap `bmkp-bmenu-menubar-menu' defined
on the pseudo-key sequence [menu-bar bmkp] in
keymap `bookmark-bmenu-mode-map':

(defvar bmkp-bmenu-menubar-menu
  (make-sparse-keymap "Bookmark+")
  "`Boomark+' menu-bar menu.")
(define-key bookmark-bmenu-mode-map [menu-bar bmkp]
  (cons "Bookmark+" bmkp-bmenu-menubar-menu))

And there are submaps off of that menu keymap.
Here's one:

(defvar bmkp-bmenu-bookmark-file-menu
  (make-sparse-keymap "Bookmark File")
  "`Bookmark File' submenu for menu-bar `Bookmark+' menu.")
(define-key bmkp-bmenu-menubar-menu [bookmark-file]
  (cons "Bookmark File" bmkp-bmenu-bookmark-file-menu))

HTH.  Maybe someone else has some better help for
keymap discovery.

(You can also use completion (`TAB') with command
`describe-keymap', to see the names of available maps,
and if you use a completion framework that lets you
filter/narrow then that might help you find maps.)

And I see now there's a typo.

Which version of Emacs is that? The following type of output goes back
to at least emacs-25:

C-h k C-c C-a RET

=>

C-c C-a runs the command mml-attach-file (found in message-mode-map),

Thank you, I see it now. I use describe-key often, but somehow I never noticed the information inside the parentheses.
