Okay another newbie question:
1)Now suppose I have a movie that has 7 keyframes, and suppose there are 8 differnt objects in it doing different things. Now I need to add a text effect that needs to run from the 3rd keyframe till 6th keyframe. When I choose an effect it lets me choose starting frame but I guess some of the effects have their own frame length so they do not let me choose the ending frame. It adds a few more keyframes. BUT it adds *only* the intermediate frames showing the text effects not all the objects from the last keyframe(last keyframe before I added the text affect). Is there another way of adding those object besides copying and pasting all of them in the added keyframes?

2)If I need to change the text effect on some text, is there a way to just pick another effect without deleting all the intermediate texts from all the intermediate frames and starting all over again? (I hate to give swish example -- but there you can have the text and then change the effects on it as many times as you want to without retyping the whole thing again).

If there is a thread or a tutorial that answers my question, could someone please point me to it or answer my question. It would be greatly appreciated.
