# Open in the user's browser

If no target was supplied, infer the URL or file most likely intended from the
recent conversation instead of asking for confirmation.

- For an existing local regular file ending in `.md` (case-insensitively), run
  `~/bin/emacs-markdown-live-preview` with the target as one shell argument.
- For every other target, run `~/bin/open` with the target as one shell
  argument.

Run the selected command once, then report the target opened.
