TextBox - scrolling without scrollbar / hidden scrollbar

Question

Hi.

I want to hide/remove scrollbars from TextBox control. When I set scrollbars value to "None" I can't mouse scroll the text. What can I do to scroll the text with mouse wheel (with custom speed of scrolling)?

I found something that works like jumping cursor between words, but I don't want this. I want cursor stay in the same place and I could scroll the text with mouse with hidden/removed scrollbar.

How to do this?
