What keyboard shortcuts work on Facebook Messenger? I've found some old articles on this, but none of the keys they give work for Mac, and some comments suggest they're no longer working for other users too.For example, it'd be good to have a key which archived a conversation. It'd also be good if there were a way to add such keyboard shortcuts through a browser extension (e.g. Greasemonkey). There are a couple of Chrome extensions for messenger shortcuts, but they only add a handful of shortcut keys, and not the ones I most need.Please don't just give keys for Windows, as I use a Mac (giving keys for other OSs too would of course be helpful to others).
