It would also be good eventually not to have to maintain the list, or indeed the dired-guess-shell mechanism at all. As for your mention of "the first M-n", as far as I can discover, the first time I press M-n, the default command, which was already mentioned in the prompt, is simply inserted at point, as if I had typed it. So is "the first suggestion that the user will get after the first M-n" actually the same thing as "the default suggestion"?

I'm sorry if I've missed something= , but I don't see what this has to do with run-mailcap.
=C2=A0
We could leave the or= iginal list intact, and add xdg-open/w32-shell-execute
to the top of the list, so it would be the first suggestion that the user will get after the first M-n.

It would = be good to discourage customization of dired-guess-shell-alist-{default,use= r}, and steer users towards the non-program-specific mechanisms. It would a= lso be good eventually not to have to maintain the list, or indeed the dire= d-guess-shell mechanism at all.

As for your mention of "the first M-n", as far as = I can discover, the first time I press M-n, the default command, which was = already mentioned in the prompt, is simply inserted at point, as if I had t= yped it. So is "the first suggestion that the user will get after the = first M-n" actually the same thing as "the default suggestion&quo= t;? (I hope so!)
=C2=A0
There is a good example how to check its availability in
`browse-url-can-use-xdg-open' that could be moved
to a more general file like simple.el.

Thanks for the poin= ter.
