open file in directory action

[Vincent Gerris]

I do not have the same know how like you both have, but I'll try to keep
the discussion focussed on the original question.
Firtsly, our question is about expending capabilities when a file manager
is used, assuming most Linux desktop apps use this.
If I look at the description here:
http://portland.freedesktop.org/xdg-utils-1.0/xdg-open.html
there already is a difference between an URL and 'the rest'.
We took a look at the xdg-open script and noticed it is determined which
file manager is being used.
There could be some added if-thens in there, arranging for the added
--select option call to the filemanager, if it is supported?
Perhaps no need for another mime type either in that situation and it would
leave other options open, right?
This assumes that a user would always want a file to be selected when a
file is opened by a file manager, which is the case on other platforms and
besides that: it is what we are looking for :).
