I am a touch typist and would like to know if there exists a way to type a question\answer with all the necessary formatting without the page automatically scrolling back up to where you input the code?

For example I mostly use Mathematics SE and would like to just see the rendered output and not the textbox for which I am entering the MathJax code.

There must be a way to dis-engage this annoying auto-scroll feature so that I can only see the rendered output as I type.

This is the simplest way I can think to word this question; if it is unclear to anyone what I'm asking then please let me know and I will elaborate.
