This here is a very bare-bones editor with MathJax support. This entire right pane is user editable. (Try it!)
The only formatting commands are:
* Italics (Ctrl+i)
* Bold (Ctrl+b)
* Highlight + Underline (Ctrl+u)
Use the standard \( and \[ combos to enter in-line and displayed math modes. Exit the math mode editing via either cursor keys or typing the closing tags \) and \]. Once the cursor leaves the math mode expressions, it will auto-render using MathJax.
