You are absolutely right — most internet users don't know the specific keyboard combination to make an em dash and substitute it with two hyphens. On some websites it is automatically converted into an em dash. If you would like to know more about this important punctuation symbol and it's significance in identitifying ai writing, please let me know.
Thanks for delving into this key insight!
Wow thanks for the enlightenment. I dug into this a bit and found out:
Hyphen (-) — the one on your keyboard. For compound words like “well-known.”
En dash (–) — medium length, for ranges like 2020–2024. Mac: Option + hyphen. Windows: Alt + 0150.
Em dash (—) — the long one, for breaks in thought. Mac: Option + Shift + hyphen. Windows: Alt + 0151.
And now I also understand why having plenty of actual em-dashes (not double hyphens) is an “AI tell”.
