browser-based text editor help!

[xataku_nakusute]

alrighty, so im making a browser-based text-editor all using javascript, k?
now it works fine and all, but i came across some problems in the process of its creation.....i created a button that is used to start bold text and when clicked again, ends the bold text. now my trouble is here: since i am making it so its all parsed and shows no html ecxept when you generate it....i dont want any <b> or </b> tags to show up....so in other words....i wanted it so when the bold button is pressed, it generates the tag, but it hides it/parses it automatically...
my code is included with this post:

If you are using a text box for people to type in, there is no way that I know to put bold text in a text box, if you are somehow using a frame, then it should automaticly parse it.
(By the way, your code isn't attached;) )
