Sorry, for spamming the thread with JavaScript related solutions to the topic request to be a GUI question. The solution for GUI was posted in the first paragraph of the previous post. But it might be useful in the future to talk about the API solution and I just remembered that there was a function from ages ago to convert a timeline string in different notations into seconds. Meaning you can even pass in the string you see in the GUI if that helps when making such calls in JavaScript:
var timeInSeconds = hypeDocument.timeIndexToSeconds('01:40,15');
hypeDocument.goToTimeInTimelineNamedAndTriggerAction(timeInSeconds, 'timelineName');
