Select keyframe at CTI / Playhead.

Hey! I got ChatGPT to make it. You have to have the layer already selected but it does select the keyframe at the playhead. I used keyboard shortcut option+K. Code here:

{
app.beginUndoGroup("Select Keyframe at Playhead");

var comp = app.project.activeItem;

if (!(comp && comp instanceof CompItem)) {
alert("Please select a composition.");
} else {
var time = comp.time;
var selectedLayers = comp.selectedLayers;
var frameDuration = comp.frameDuration;

if (selectedLayers.length === 0) {
alert("Please select at least one layer.");
} else {
for (var i = 0; i < selectedLayers.length; i++) {
var layer = selectedLayers[i];
selectKeyframesAtTime(layer, time, frameDuration);
}
}
}

app.endUndoGroup();

function selectKeyframesAtTime(group, time, frameDuration) {
for (var i = 1; i <= group.numProperties; i++) {
var prop = group.property(i);

if (prop instanceof PropertyGroup) {
selectKeyframesAtTime(prop, time, frameDuration);
} else if (prop instanceof Property && prop.numKeys > 0) {
for (var k = 1; k <= prop.numKeys; k++) {
var keyTime = prop.keyTime(k);
var isOnCurrentFrame = Math.abs(keyTime - time) < frameDuration / 2;
prop.setSelectedAtKey(k, isOnCurrentFrame);
}
}
}
}
}

It's been six years since OP and three years since last reply. I now am getting bogged down by this lack of functionality, too. Adobe, any movement on this? Of course I will submit the feature request if it doesn't already exist, and comment if it does.

Does anyone have a working link to this script?

That script looks interesting. But what about the already existing J and K shortcuts? They take you to the previous/next visible keyframe (regardless of layer).

If you have a lot of keyframed properties visible it can be a bit of a pain, but if you just show the one(s) you want to play with, it's a huge time saver and also can eliminate errors where your playhead is not perfectly overtop of your keyframe (something which can happen  when scrubbing with the mouse, not so much with clicking on the prev/next arrows next to the property).

Someone wrote a script that I think does exactly what you need:

Select Next Keyframe (in selected property) script

Interesting idea. I couldn't find any method to assign an AE keyboard shortcut to select a single keyframe either. However another idea would be to use the Operating System to assign a key to simulate a mouse click - although this would require using the keyboard to also position the mouse. Here's what I found:
