I always get en and em confused. They are all just dashes to me :-).

The "Nothing else: no lists, tables, links, quotes, images or rules" is from the docs indicating that these things are not supported.

I, too, was confused for the longest time, but the secret is in the names.

En dash is the width of an “n”. Em dash is the width of an “M”, so a little wider.

Not unlike how in the trades, a tee is T-shaped, a wye is Y-shaped, a delta is Δ-shaped. Spelled-out letters aren't always geometric metaphors, but it's a thing.

Then you've got the first syllable of Ω (omega) being a homophone of Ohm, for what that's worth. From there we have ℧ (mho) for conductance... It's all quite clever. But I digress; I'll get back to emceeing and deejaying, cueing these elpees after a quick pee, okay?

Different fonts use different lengths (sometimes en dash is the width of an uppercase “N” instead of lowercase, sometimes it’s half of the em dash which itself is `1em` which may or may not equal the width of the “M”...) But it’s a good way to remember that indeed, yeah!

> I always get en and em confused

Yeah, it’s somewhat a typography-nerdy thing :–) (gosh that looks terrible probably; edit: actually it’s surprisingly fine)

> indicating that these things are not supported

Of course, but it does sound a bit unnatural IMO. Then again, I’m going by the vibes here.
