No, there aren't. I simply copied the example above for the events section on the startpage, event, "loads", to run the following javascript
//This adds a new marker where the user has clicked.
google.maps.event.addListener(map, 'click', function(event) {
marker = new google.maps.Marker({position: event.latLng, map: map});
alert("The user picked latlng " + event.latLng + ".");
});
I'm new at this. Any help is greatly appreciated! 
What does display this alert? There is specified that this code executes on "click" event, not on "load" event.
My intention is to allow the user to long click on the map, and store the latLng coordinates into a variable (and then later put them into the system clickboard.)
The alert is just to test and see if the long click returns the latLng.
I may need to start "from zero", from the beginning.
My map component is "googlemap_2" so to trap the click location, in startscreen, under the Events section, for event "loads" I know I need to add a listener, with "GoogleMap.setOnMapLongClickListener(OnMapLongClickListener)" but I'm not sure of the syntax and clauses.
Then, on the "googlemap_2" component Events section, I could add the alert using "onMapLongClick (LatLng point)", but again, I don't have the syntax clear. If you can give me a simple example of the code to use, I can probably work out the rest. Thank you!
Your site and platform are fantastic, by the way.
