This article deals with the last two sections of this window.

Please see Styles / Icons - Styles for the first three.

Tick Marks

You can set the interval for Tick Marks. This is set in km or miles depending on your settings in Settings->Units.

For the tick marks or arrows to be displayed on the map, you need to have your route or track using a Line Style which has them enabled.

Enable Scaling

This allows you to decide how map data is printed on the screen - either at a constant size in screen pixels, or if you wish for it to scale with the map as you zoom in and out.
