Connecting Two Keyframes To Start And End Point of Workspace
Is it possible by any chance?

Do you mean the work area? Expressions don’t have access to the work area start and end times. Scripting does, so you could do it with a script, but it wouldn’t adjust automatically when you change the work area.

Yes, work area,
Than maybe the script can have a refresh button for when I want to update it to the new work area length?

It could, but that would require a UI for the script, which is a bit of work. Here’s how the basic functionality might look though:
function setKF(){
var myComp = app.project.activeItem;
if (! (myComp && (myComp instanceof CompItem))){
alert("No comp active.");
return;
}
var myProps = myComp.selectedProperties;
if (myProps.length == 0){
alert("No property selected.");
return;
}
var myProp = null;
for (var i = 0; i < myProps.length; i++){
if (myProps[i].numKeys >= 2){
myProp = myProps[i];
break;
}
}
if (myProp == null){
alert ("No property with 2 or more keyframes selected.");
return;
}
var tStart = myComp.workAreaStart;
var tEnd = tStart + myComp.workAreaDuration;
var myExpr = "t = linear(time," + tStart + "," + tEnd + ",key(1).time,key(numKeys).time);\rvalueAtTime(t)";
myProp.expression = myExpr;
}
setKF();

Thank you so much.
