aenhancers

I know I can clear all keys of a property through the following code:

    for (var index = property.numKeys; index >=1; index--) {
        property.removeKey(index);
    }

However, when I actually practise it, it consumes quite a long time, if the property has many keys. I don't know why it is so time-consuming. If I manually click the clock button in the AE instead of using the code, it can be quickly done.
So is there any method to quickly clear all markers of a property?

A faster way to do this would be to select the keyframes you want to delete and execute the in-app "Delete" command

something like this:

app.executeCommand(2004); //use this to make sure nothing is selected, in-app deselect all command
property.selected = true; //select the property, this also selects all the keyframes of that property
app.executeCommand(21); //in-app clear command

This is way faster than deleting the keyframes using a loop.
