[Orgmode] Choosing external app at runtime?

[Simon Guest]

Hi all,

When I follow a link, Org mode knows what application to use.  Except
that sometimes I want to override that choice.

For example, I have a collection of PDF files.  Mostly I want to open
them in my statically configured PDF viewer, which is fine.  But
sometimes I want to open one in Xournal, say, to annotate it.

My mail client Wanderlust will ask me in cases like this: if multiple
mailcap entries match, I get to choose when opening the attachment.

Any chance we could do a similar thing in Org mode?

cheers,
Simon
