Use backtick's ` for inline code (like in Markdown).
Automatically fix quotes in code tags/code blocks.
Link to a section of text/heading easily.
Tab does nothing (normally it will do the browser default focusing on the next input).
Pressing enter in a code block will do a new line instead of making a new "paragraph" inside the code block. It moves the extra space to the bottom of the code block to be manually deleted later (can't do it automatically since it broke the editor when I did). You'll also need to use Left/Right instead of Up/Down when on the empty line you just made. You can use Up/Down normally if when the line isn't empty.
