text writing

How to create the effect of text writing easy? Are there any other ways besides "append text"? For example, I have a large text, and I need to write it letter by letter, at regular intervals 0.5 seconds. Can I make it as anything other than a "wait 0.5 seconds" and "append text"?

A couple of neat ways of doing it, some other useful info there too.

thanks! But how to make time intervals between sentences? example: I need to make that the first sentence was a little pause before displaying the second sentence. How to do it?

Take Ashleys one event example, but instead of stepping through the source text, take an array. Make the array two dimensional and store in the first column the sentences and in the second, the time to wait till the next sentence....
