How to create typewriter effect?

Few ways to go about this. The least complicated is creating a variable first, something like "myURL". Then create shape (such as a square) just off of your stage. Create a trigger on this shape so that when the timeline starts, your myURL variable is set to the full URL.

Make copies of this shape and delete an additional letter from each copy until you end up with one shape with a single letter. Now arrange your shapes on the timeline, pretty close together, to produce an animation that builds the letters one at a time.

Now when you add %myURL% to a text field, you can position it wherever you want without having to worry about a one letter at a time build arrangement. 

If you're comfortable with JavaScript, you could also use a JavaScript trigger to generate the text sequence.

Ok I will try the least complicated suggestion Steve - Thank you - JavaScript ... beyond me at this point

Thank you!!!

Hi Christina, Steve's idea is very clever but I built one using the "old school" method which is adding each letter as a separate text box to the timeline. To make it seem more realistic you should use a font like new courier and drop some of the letters a bit.  Here is an example of a title screen where I used this method.

I just updated the link to this one so it should work now. Example

Cool & simplistic Nancy, nice job. I do like the dropped 'e' effect. Go back a few years and yeah, that's realistic.

You could also add animations with a punch sound for when the typewriter "fingers" hit the page, revealing the letters. You would need to be careful with the layering here so the "fingers" do look like they are coming from within the typewriter.

Nancy great idea!!! Thank you I love your example!!

I've used Nancy's example when showcasing a phone number.   The numbers appear as the narration reads it aloud.  Very effective, but equally time consuming.

I hear you about the time consuming part

Nancy - I took your idea because i'm a little "old"  school that is

It worked great - thank you all for your help and input!!
