The default split screen view includes a Google map:
GSAK currently uses "Server side" Google maps for displaying waypoints and their children. This is a public interface (in accordance with Google Maps TOU) and this server interface can be used "stand alone" see this link
Hide Map - Click on this button when you do not wish to see the Google map in split screen. There are times when you don't need to see the map, and having it display all the time will slow down the rendering of your split screen.
Splitscreen - This will show just the full Google map in the spit screen.
Browser - This will show the full Google map in your default browser
Hover your mouse anywhere over the map to see the zoom controls and map selection buttons:
Click on the Waypoint for a pop up bubble:
Right mouse click for a menu of options:
Zoom Here - Zoom and centre the map at this location
centre Map here - centre the map at this location
Add Child Here - Aadd a child waypoint (it opens the child add dialog) with the coordinates at this point
Add Waypoint Here - Add a normal waypoint (it opens the waypoint add dialog) with the coordinates at this point
Coords to clipboard - Copy the coordinates of this point to the clipboard (WGS84 datum, Degress decimal format)
Run Map Macro - Run a GSAK macro. This option allows you to fully harness the power of transferring coordinates from Google maps to GSAK. It is a similar to "Coords to Clipboard" option, but when you select this option, GSAK will run the macro configured via "Tools=>Options=>Advanced"
So that your macro can determine the coordinates of this point there are two system variables
$_GoogleLat
$_GoogleLon
In your macro you could then do anything you like with these coordinates. For example, set a GSAK centre point, set a search radius, etc. If you have different things you want to do at different times, then just front end your macro with a form that gives you all the options you want to perform.
To develop your own Google maps that display more that one cache on a map see the MyGME macro
