When adding or editing a Custom Marker, you have the ability to attach up to 10 web links to further extend a marker's content by linking to additional information and/or sources on the web. To attach a web link, you must be in the process of creating a new marker (click here to learn more about adding markers), or editing one of your existing markers (click here to learn more about editing markers).
Start by clicking the "Add" button under the web links attachment list.
This will open the "Attach Web Link To Marker" window.
Enter the URL to the resource you wish to link the current marker and enter a brief description of what it is you are linking to.
When you're done, click the "OK" button.
This will close the "Attach Web Link To Marker" window. You should now see newly-added web link in the web links attachment list. Next to it, you will notice these two buttons.
The edit button is for editing the URL or description of a web link. The detach button is for removing the web link from the current marker.
