Define Keyboard Shortcut for "Open in Emacs"

Define Keyboard Shortcut for "Open in Emacs"

Hi

I would like to open pdfs in emacs (using pdf-viewer) but there is only
a shortcut (C-c C-o) to open a pdf externally, and no shortcut for the
menu item below "Open in Emacs" in the context menu.

How can I define a shortcut for this command (or re-use C-c C-o)?
Thanks

Rainer

It's too bad there's not some way to find out all the different things C-u
does to commands when used...

Thanks - C-u C-c C-o works for me

If you want C-c C-o to open in emacs, you can configure your 
org-file-apps:

#+BEGIN_SRC emacs-lisp
  (eval-after-load "org"
    '(if (assoc "\\.pdf\\'" org-file-apps)
         (setcdr (assoc "\\.pdf\\'" org-file-apps) 'emacs)
       (add-to-list 'org-file-apps '("\\.pdf\\'" . 'emacs) t)))
#+END_SRC

Alternatively, if you are on Linux, you could make your 
emacsclient your default pdf-viewer:

#+BEGIN_SRC shell
  xdg-mime default emacsclient.desktop application/pdf
#+END_SRC

Then the external program called by C-c C-o would also be emacs =)

Best,

What is emacsclient.desktop exactly ? On my slackware, there is
nothing named like this.

Thank you for both your tip and probable answer.

Inside a desktop environment (e.g. GNOME, KDE, Xfce), xdg-open
passes the arguments to that desktop environment's file-opener
application (gvfs-open, kde-open, or exo-open, respectively).
When no desktop environment is detected (e.g. using Openbox), 
xdg-open will use its own configuration files, emacsclient.desktop 
is the call to the emacs server, if you do not use the server you 
could use emacs.desktop instead.

Best,

Thank you very much for these clarifications. Should I expect
anything from xdg-* when not using a desktop environment at all ? (I
am using something home-brewed where I could add support for
something like this but that's not for now).

Also, can you share an emacsclient.desktop file ?

Regards

I am not sure. You could try xdg-open in any file from the 
terminal, to see if it works as expected

> Also, can you share an emacsclient.desktop file ?

That is not a file, but how xdg identifies emacsclient. You can 
find more about it here:

Lovely ! It just works.

Good idea - I will keep this in mind and see.

Nope - Mac.
