Expression selector
I’m having a hard time writing expression selector expressions as there doesn’t seem to be much documentation out there.
If it is possible, how could I target on characters by their index that have changed in the last frame. And I want to combine this with a linear function to change the influence so that if they have changed 1 frame ago = 100… 10 frames ago = 10, 11 frames ago = 0.

Here’s a simple example that will need more complexity if there are multiple lines, or if the number of characters changes:
curChar = text.sourceText.value[textIndex-1];
val = 100;
t = time - thisComp.frameDuration;
while (val > 0){
prevChar = text.sourceText.valueAtTime(t)[textIndex-1];
if (curChar != prevChar) break;
t -= thisComp.frameDuration;
val -= 10;
}
val
