Opensuse/KR47's Kmail2 Kontact seems to come preconfigured with a "(click to) Find Address" URL string to open an address' location in OpenStreetMap using the MapQuest API.

It's clearly configurable to use OTHER API/Service strings.

What's the right format for that string in order to have the clicked-on Address show up in *Google Maps* in KDE's 'Default Browser', instead? I've tried various strings I've found scattered around the web, but the best I've done is to open Firefox and end up at a 'generic' Google Maps page. No finding of the address I specified.
