14 punctuation marks that you never knew existed

I did know that some of them existed, actually. The full list is here. It's an annoyingly ad-full page but worth persevering with to learn that marks like these exist (comments are from the original site, not mine):

Because Sign

This one's so cool. It's like the "Therefore" sign, but upside-down, and it means because.

Exclamation Comma

Just because you're excited about something doesn't mean you have to end the sentence.

Hedera

Hedera is Latin for ivy. Why that is relevant here is not very clear at all, but this little glyph was used back in the day to mark paragraph breaks. Seems like it was probably really hard and annoying to draw, but it looks nice.
