Enforce internal/external open of a link?

[karelt]

Hi!

If I have a file extension registered among those to open internally (Tools/Options/Browser/File extensions to display in internal browser view), is there an easy way to enforce opening a particular file link with an external application, pls?

And vice versa? If a file extension is not listed among those to open internally, can I still somehow enforce a particular linked file to be opened internally?

Many thanks in advance!

Best,
Karel
