Can I create collapsible headers in Paper?

Of course you can engage!

You can add an H1 or H2 by using the formatting toolbar or the shortcuts listed below.

• H1: Type # and press space, then type your header
• H2: Type ## and press space, then type your header
• H3: Type ### and press space, then continue typing (you can also add an H3 by highlighting and bolding an entire line of text)

You can also make H1 and H2 headers more bold by highlighting and bolding them as you would with any other text.

To collapse or expand them, click on the downward arrow on the left of the header you'd like to take these actions on. 

I hope this helps and please let me know if there's anything else you'd like to ask too. Thanks for using Paper!
