Hotlink Waypoint Code (File=>Print)
Select this option if you would like GSAK to link the code column to the URL allocated to that cache. For example, this is usually the address of the geocaching.com page if this waypoint was from a GPX file from Groundspeak.
This would normally not be required for printing. However, as you can also use the HTML that GSAK generates to upload to a website or just view on your computer, this option allows you to "hot link" the code in the HTML display.
