HELP - Google Earth

Howdy ,

I am in the process of organizing and re-naming hundreds of waypoints into new files . All the waypoints have been transferred to Google from my old Magellan .

In the MY PLACES file , I cannot select more than one way point at a time and yet I have hundreds to cut and paste to new files . It will take me forever to do them one at a time .

Does anybody know how to do this ( select more than one ) - the shift keys etc do not work .

Thanks ,

Willie .
