    You could try something like this to time the reveal of each word with layer markers:


    freq = 3;
    decay = 5;
    startVal = [100,100];
    endVal = [0,0];
    dur = 0.1;

    try{
    t = time - marker.key(textIndex).time;
    }catch (err){
    t = 0;
    }

    if (t > 5){
    endVal
    }else if (t > 0){
    if (t < dur){
    linear(t,0,dur,startVal,endVal);
    }else{
    amp = (endVal - startVal)/dur;
    w = freq*Math.PI*2;
    endVal + amp*(Math.sin((t-dur)*w)/Math.exp(decay*(t-dur))/w);
    }
    }else
    startVal

    Perfect! My goodness. I feel like every After Effects user needs to work together on getting a statue erected in your in your honor. You just saved me a ridiculous amount of time.

    Thank you VERY much.
