Executing shell commands on files

[iagogv3]

This is a question/doubt (not sure if there is another place to ask) or a FR. On dired-mode, if I want to execute a shell command over the file where I place the cursor, I can do !, that is dired-do-shell-command?

Is there any similar command for deft?

The goal is that there may be files which I want to open with their default apps, not emacs. In Linux I would do !xdg-open, while in Windows I would do !open. May I get at least this goal with deft?

Thanks!
