As you move the map center to the location where you want to know the latitude and longitude, you'll see latitude, longitude, and TM coordinates information and addresses for that location. Click on the [Current Position] icon in the upper right corner of the screen and wait for a while to move the map to its current position and display the icon.
If you click the clipboard icon in the coordinate information panel, the coordinate information is copied to the clipboard, and you can paste it in another application.
Press the Add (+) button at the bottom of the screen to add the current location to the bookmark or hide / show the bookmark on the map. You can also delete bookmarks from the bookmark list by sliding them to the left, or select them to move the map to that location.
