Hey everyone

I'm trying to make a rich text editor with Actionscript 3 and Flash CS3. I have a textfield, and a bold, italic and underline button. I too have a align left, right and center button.

But how would you go about editing the text in the textfield?
How can I tell flash to e.g. make the text I have selected in the textfield bold?

If anyone have some quick suggestions, I would be really great.
