1. The current view of the map can be panned to a new position by pressing the left mouse button and dragging the map.

2. After saving a route and closing the Compass Tool, new legs may be added later by importing the route using the 'Import Route' menu button.

3. Bearings are given in both absolute map numbers, and compass-corrected for the local magnetic declination value, which is also listed. If your compass lets you adjust the magnetic declination, you have the option to do that and use the uncorrected map bearings.
