How is that highlighting done?

Hi @wolfman Maybe my preview is screwed up because if I try to highlight > this text it doesn't show correctly. Just sticks a greater-than in front.

I'm referring to text in a sentence highlighted. Here's an example from @marfig: Desktop keyboard shortcuts don't work with conky - #3 by marfig

Blockquote looks good for multiple code lines, though:

Code line 1
Code line 2

See how this posts.
edit: yeah, tried to highlight "this text" in first sentence using blockquote - didn't work.
