To find a lot-long in Streets & Trips you need to,

1. Pan and zoom the map to the desired location
2. Place the mouse cursor over the map area for which you need the lat-long
3. Then press Ctrl+Alt+C from the keyboard.

This will capture the lat/long of the cursor location into the clipboard, you can then past this into a notepad or a email client and share it with others. The copied text will look like this 47.59408°N 122.32092°W or the format can be changed from under Tools – Options (Settings Tab)

As with previous versions, you can search a point on Earth using latitude-longitude coordinates. Streets & Trips allows you to find a place by typing in the lat/long in the Find dialog

Lat/long helps you locate a place where there is no street address, this is especially  useful to find new communities, parks and other rural areas.
