Re: pdf files with openwith only, and only this.

Dear Tim, John and Colin,

You are right Tim, for Gnus, the solution to my problem was here :

https://www.emacswiki.org/emacs/MimeTypesWithGnus

and here:

https://lists.gnu.org/archive/html/info-gnus-english/2016-04/msg00002.html

But I just realize that Gnus gives the choice to open "internally", or
"externally"... :S

Best wishes and many thanks for your very kind help,

Jo.
