lemmy also (unofficially) supports footnotes.[^1] you may want to view this in a browser^[as it currently doesn't render in any mobile clients]^[also note the differing positions of the caret]

additionally, with no markdown linking at all, the web interface^[and i believe most apps] automatically turns [!community@instance.tld](/c/community@instance.tld) into a link

[^1]: with two different syntaxes

Italic Italic

Bold Bold

just a random bold italic quote

Link to a post with a table inside a spoiler

And another good test

Something I haven't seen most apps do (but the webui does) is converting (tm) => (tm)

no clue if there are similar substitutions out there, would probably need to check the code to confirm

!syncforlemmy@lemmy.world

#i take it back third image in link is NSFW when I copied the code for some reason! It's just rick roll on the actual link though? Sorry, this formatting is still new to me.

Testing from this post (nsfw instance, but sfw post showing markdown for multiple photos)
