Automatic newline in textarea

Question

Using jQuery, how can I make a textarea that automatically adds a new line when inserting text when the cursor is near the end.

The width of the textarea is dynamically

Answer 1

This is a really nasty problem to try and solve. I'd be going down either 1 of 2 pahts. 1 just use the text area as is or 2 using a nice jQuery editor which makes the text look nice.
