Add / delete a point or shape - to ADD: 1. with an address: enter an address and click on 'Add', the point will automatically appear on the map. 2. Draw a point or shape directly on the map: - first zoom in on the map with the + and - buttons until you can clearly see the street where you want to place the point - click the marker button (3rd top right on the map) and drag the marker to the right place, or select the line or polygon button and start drawing. To DELETE an incorrect marker or shape: - click the arrow button (select button) - now click on the marker or shape you want to remove - click on the trash button. The marker has now disappeared and you can start again if you want. To EDIT: you can't edit point or shapes once added. Simply delete them and start again.
