Magnetic tool

Just started working in Silhouette and I can not figure out how to draw background and foreground strokes for keying? How do you get to the strokes mode?

Silhouette Standalone: See Magnetic Freehand tutorial on page 89 of the user guide.

The user guide can be opened from within Silhouette by selecting Help > User Guide.
