typewriter animations

[Mo White]

At the moment to do typewriter animations in Flash im doing it manually

frame by frame

that is to say if i wanted the word 'hello' to be typed id go backwards from

frame 5 and type


hello

hell

hel

he

h


and then when it plays it look slike hello is typed out.

this is really tedious. is there an automated way or a third party tool that

can do this for me?
