Compose key, hyphen, hypen. Because while it's a less common usage, visually I prefer the shorter en dash – over the em dash — anyway.

Also for people missing the Unix-style compose key on Windows: https://wincompose.info/. Memorising numeric codes is for chumps :)

I feel like this is more likely to lead you astray than anything. An LLM bot will immediately know the alt code, while a real person will only know it if they use Windows. Lots of people use Linux, or mobile keyboards.

I always just google 'em dash' then ctrl+c it.

Or if they start explaining what a compose key is; also human

What if they don't know the code and just use a keyshift instead?

Opt shift hyphen. What's an alt code? 🍏

meh - I just use a dash and move on.

for me it's just altgr+caps followed by tapping - thrice, way better use of the caps lock key. thank u xmodmap
