+                 Brush Spacing
+
+                   The space between each position where a brush is applied
+                   to the canvas can vary. Some brushes (such as the
+                   footprints and flower) are spaced, by default, far enough
+                   apart that they don't overlap. Other brushes (such as the
+                   basic circular ones) are spaced closely, so they make a
+                   continuous stroke.
+
+                   The default spacing of brushes may be overridden using by
+                   clicking within the triangular-shaped series of bars at
+                   the bottom right; the larger the bar, the wider the
+                   spacing. Brush spacing affects both tools that use the
+                   brushes: the "Paint" tool and the "Lines" tool.
+
+                   (Note: If the "nobrushspacing" option is set, Tux Paint
+                   won't display the brush spacing controls. See the
+                   "Options" documentation.)
