index Return type: Number.

Returns the index of the keyframe.

MarkerKey attributes

You can access values for composition-time markers and layer-time markers using the same methods. Access layer-

time markers through the

thisLayer.marker object; access composition-time markers through the

thisComp.marker object.

For the purpose of expressions, markers are a special kind of Key object, so you can use methods such as

nearestKey(time) to access markers, and markers also have time and indexattributes. The index attribute is not

the number (name) of the marker; it is the keyframe index number, representing the marker’s order in the time ruler.

Expressions have access to all of the values for a marker that you can set in the Composition Marker or Layer Marker

dialog box. This expression on a text layer’s Source Text property displays the time, index, comment (name), chapter,

URL, frame target, and cue point name for the layer marker nearest the current time, and whether the marker is for

an event cue point:

m = thisLayer.marker.nearestKey(time);

s = "time:" + timeToCurrentFormat(m.time) + "\r" +

"key index: " + m.index + "\r" +

"comment:" + m.comment + "\r" +

"chapter:" + m.chapter + "\r" +

"URL:" + m.url + "\r" +

"frame target: " + m.frameTarget + "\r" +

"cue point name: " + m.cuePointName + "\r" +

"Event cue point? " + m.eventCuePoint + "\r";

for (param in m.parameters){

s += "parameter: " + param + " value: " + m.parameters[param] + "\r";

}
