To anchor a virtual position somewhere is to virtually replace your current position for a new position in the map.
Once fixed, information displayed on proximity fields and ‘Pin’ mode will be based according to the new anchored position, and not on your real position. Moreover, if 'Anchor here' is pinned, options such as 'Re-center' map will be applied to the anchored waypoint instead of your current position.
In order to anchor a position reproduce any of these
options:
•'Map window > ‘Pin’ mode > Anchor here'
•'Main menu > Files > Item > Contextual menu of waypoint > Anchor here'
In order to unpin the fixation and restore the current
position as the default one, press: ‘’Pin’ mode >
Unanchor’.
