A refresh key at the very least does seem like a good idea (perhaps also, for local files, the ability to turn on a "watch" mode for the current file and reload it if it appears to change). |

I love the idea of monitoring for changes! It could be done either by using a cheap timed loop or something more sophisticated like watchdog. |

Yup, something like that would be the plan. Ideally first I want us to make some enhancements to the Textual Markdown widget that would help with this working really well (things that would help with keeping position in the document so it doesn't keep jumping back to the top, etc). |

Consider this a "hits most use cases" initial take on #44; I think this is needed anyway. Reloading based on external input should follow later, but I think those things make more sense when I can make a best-efforts attempt at reloading and ending up at the same position (which would help make things feel more like a live-edit viewer). Anyway, that's a different request/PR. This is about a simple refresh.

It would be great to have a way to refresh the content of a file using a key combo but also using some kind of programatic way (socket? external command?). This would be perfect for using the viewer in a preview splits with text editors like Vim and/or Tmux environments.
