Just a heads up, you can actually use !m or !gm to access Google Maps directly.

There's also !osm for OpenStreetMaps.

DDG has a direct bang for google maps

!maps

The have a searchable list for every bang they support. https://duckduckgo.com/bang

I just don't see how chording keys is convenient. !g is awkward to type on a keyboard.

You can also use !gm directly!

!wbm wayback machine (urlencoding issues but still)

!yt

!cache
