Selected text highlight

Hi, I would like to highlight (set background or textcolor) the selected text in a textarea. Is it possible?
I select the text, copy it, and set the focus to another control. I cant have the focus on the selected text, so i need to color the selected text, so the user knows what he selected.

Read specifically Selected Text Properties:
TextArea1.SelStart, TextArea1.SelLength, etc.
