 *focus\_follows\_mouse* yes|no

+*focus\_wrapping* yes|no|force
+	This option determines what to do when attempting to focus over the edge
+	of a container. If set to _no_, the focused container will retain focus,
+	if there are no other containers in the direction. If set to _yes_, focus
+	will be wrapped to the opposite edge of the container, if there are no

+	to the opposite edge of the container, even if there are other containers

 *font* <font>
