Probably something similar to this:

m = marker;
n = m.nearestKey(time).index;
if (time < m.key(n).time) n--;
r = 0;
if (n > 0){
  n = (n -1)%4;
  if (n == 1)
    r = -5
  else if (n == 3)
    r = 5;
}
r

It should work either way, but the target has to animated, either by keyframes or an expression applied to the layer itself or its parent. If you just drag it around, nothing will happen.

Hmmm…. It works for me. The child will mimic the movement of the target, even if the target has no movement of its own and is only animated by the motion of its parent. I must be missing something…

I think it will look something like this:

minHold = .1;
maxHold = .75;
t1 = key(1).time;
t2 = key(2).time;
d = t2 - t1;
if (time >= t1){
  t = tPrev = t1;
  while (t <= time){
    tPrev = t;
    seedRandom(tPrev,true);
    h1 = random(minHold,maxHold);
    h2 = random(minHold,maxHold);
    t += d*2 + h1 + h2;
  }
  tDiff = time - tPrev;
  if (tDiff < d)
    valueAtTime (t1 + tDiff)
  else if (tDiff < d + h1)
    key(2).value
  else if (tDiff < 2*d + h1)
    valueAtTime(t2 - (tDiff - (d + h1)))
  else
    key(1).value;
}else
  value

Try it like this:

target = thisComp.layer("Target");
offset = target.toComp(target.anchorPoint) - target.toComp(target.anchorPoint,0);
value + offset

[Dan Ebberts]

Try this:

s = effect("Slider Control")("Slider");
t = linear(s,0,100,key(1).time,key(2).time);
valueAtTime(t)

[Dan Ebberts]

Try this for Start:

(thisProperty.propertyGroup(3).propertyIndex - 1)*2

and this for End:

(thisProperty.propertyGroup(3).propertyIndex - 1)*2 + 1

Try this for the first one:

words = text.sourceText.split(/\s+/);
words[textIndex-1][0] == "@" ? 100 : 0

[Dan Ebberts]

Maybe like this:

seedRandom(index, true);
offset = random([-50,-50],[50,50]);
value + offset

You could run a little script like this:

var comp = app.project.activeItem;
var layer = comp.selectedLayers[0];
var props = layer.selectedProperties;
for (var i = 0; i < props.length; i++){
	if (props[i].canVaryOverTime && props[i].numKeys >= 2){
		var t1 = props[i].keyTime(1) + comp.frameDuration;
		var t2 = props[i].keyTime(2) - comp.frameDuration/2;
		var t = t1;
		while (t < t2){
				props[i].addKey(t);
				t+= comp.frameDuration;
		}
	}
}
