A
Intro, is more complex as the sentences or text
blocks do NOT necessarily appear one after each other, as
it's possible (when the effect tab is set to intros)
to set the incoming time of each text effect (the moment
when the effect appears) and the duration (the time
the text remains on screen) with these features you can
for example make an animation whereby each sentence appears
one after each other, and after they are all displayed they
will fade out all at once. (Back
