Changing text format for portion of text

programming flash
1

I have a textfield with 6 lines of text. Is there a way to change the color and maybe the size of ONE word within this textfield? When the user clicks a button I want a certain word to stand out. Then when they click again I want that word to go back to normal and have another word change.

Like this.


var string3:String = "SERVICE_NAME            : messenger";

[COLOR=red]SERVICE_NAME[/COLOR] : messenger //First click
SERVICE_NAME [COLOR=red]: messenger [/COLOR][COLOR=black]//Second click[/COLOR]

Thanks in advance.
