Color coding certain regex match in a textarea?

Question

Is there any way via JS to highlight text inside a textarea that matches a specific pattern?

I am loathe to use a fully WYSIWYG editor as I just want to highlight certain text (references in scientific writeups, they become very cumbersome to read over).

Don't think one can do that, can't have html inside a textarea. The best way is probably to replace the textarea with an `iframe` which can have html in it. I suppose you'll have to use JS to catch the key presses and enter the content as well though. — ianbarker, Apr 25 '12 at 16:19

textarea can not support different colors. So your answer is you can not do it in a textarea.

Take a look at this article: Javascript - Change font color of certain text in textarea

Summarized, you cannot add tags inside of a textarea, so you cannot modify the font/style of text contained within it.
