It is so irritating that people now think you've used an LLM just because you use nice typography. I've been using en dashes a ton (and em dashes sporadically) since long before ChatGPT came around. My writing style belonged to me first—why should I have to change?
If you have the Compose key [1] enabled on your computer, the keyboard sequence is pretty easy: `Compose - - -` (and for en dash, it's `Compose - - .`). Those two are probably my most-used Compose combos.
