I've discovered that when I use certain combinations of characters I get some automatic formatting. I want to use more of these and I haven't been able to find anywhere these are documented. Where can I find a list of supported shortcuts? Examples I know of: '----' and '====' become a horizontal line '' becomes a checkbox '* ' becomes a bullet list '1. ' becomes a numbered list I'd really like to have similar autocorrect for headings, code blocks, quotations, bold, and pretty much anything I can do with markdown.
