Basic familiarity with the paragraph styles in Word is like a 20 minute task.

If you are using markdown, you already understand the conceptual basis for it, so you just need to understand how it's implemented over there.

I'm not arguing that it is something you should do, just rolling my eyes at "I would be lost".

Not lost because it's hard to learn, but because I don't like writing in ms office products. It's not just word, I write formated long emails in outlook as well.
