Back before llms poisoned it (and I still used Windows), I had the alt code for em dash memorized (prob still have the muscle memory to do it, but not currently at a numpad) because I really liked using them in papers I had to write for school. I read lots of books back then, and recognized how much I preferred using em dashes to commas in specific cases.

I hate that I can't use them anymore lest I be mistaken for someone who uses llms
