Navigation Buttons (Waypoint=>Add/edit)
The navigation buttons allow you to move through the records in the database one record at a time, or to go to the first or last record in the database. Hover your mouse over the individual icons to see a help tip on their function.
Movement is always relative to the current record (indicated in the first column of the database view by a black triangle pointing to the right).
When you click on any of the navigation buttons it has the same effect as clicking the OK button first. That is, any changes you have made to the current waypoint are committed to the database. So, you can set a filter on a group of records you want to change, then change them quickly by altering the required fields, and then clicking the Next button.
