Geolocation Plugin=>How to

Despite reading the instructions, how to add GEO-Location info for each item is still vague.

After a CSV import, I edit the item and click <MAP> and then what do I enter in the "Find Your Location Via Address:" field and in what format? Because despite entering an address, no information is saved.

Also:
Is there a way of populating geolocaiton coordinates during CSV import?

There are three steps here:

1. Enter an address.
2. Click "Find By Address"
3. Click "Save Changes"

Alternately, you can click on the map to choose a location and then click "Save Changes."

After entering an address, nothing occurs and save does not work.

Actually, I am able to make work by using alternative method.
