Zoom in on the map
Press the + key to zoom in on the map in Google Maps. It is listed for Windows, and no Mac version is documented here. It works in the browser version.
Where it works: Map in focus
On a US English keyboard this character needs Shift and the equals key. The shortcut itself is unchanged.
Where this comes from
