Typewriter effect

I’m getting there by fail & try. With help of Duncan, I can now save the files as “SAVE AS”.
Typewriter effect is so use full. I’ve just tried. Jungled with it. With this effect some how I can’t able to lined them.
Meaning with this is If I add a sentence line 1 and then add another sentence to line 2 and 3 it doesn’t cut at the end of the sencente.A few words adds before goes to new line. Default settings are quite alright.
Am I missing point?
