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.
