Markdown Writing Mode
Have a special mode for entering Markdown text instead of RTF, that understands Markdown constructs including its own bold/italics, links, code entry, etc. with no interruption from the usual RTF formatting tools.
This is a copy of the idea that has 150votes for windows.

Put all the votes I could on both Markdown request features. Ditched Evernote for lack of markdown, hoping OneNote actually addresses this in a "reasonable" amount of time.

I voted for the Windows idea and voted for this one. Since learning Markdown for text formatting in other apps (Slack and Trello), I can't live without it. Being able to quickly format text without taking your hands off your keyboard or interrupt your typing flow is critical.
