Change font type of an editable field based on user input

I am trying to set up a movie that will let users type in some text and then choose the font for that text.

The movie will do more than this, but this is what has me stumped...

Can action script change the font face/type/size?
If so, what are the commands?

I am using Flash 4 now, but should be able to upgrade soon to Flash 5.

You could use the keypress function, I.E A=Arial, it transfers to arial font.
