+=== Popups during fullscreen mode
+
+When you are in fullscreen mode, some applications still open popup windows
+(take Xpdf for example). This is because these applications may not be aware
+that they are in fullscreen mode (they do not check the corresponding hint).
+There are two things which are possible to do in this situation:
+
+1. Just ignore the popup (don’t map it). This won’t interrupt you while you are
+ in fullscreen. However, some apps might react badly to this (deadlock until
+ you go out of fullscreen).
+2. Leave fullscreen mode. This is the default.
+
+*Syntax*:
+-------------------------------------------------
+popup_during_fullscreen <ignore|leave_fullscreen>
+-------------------------------------------------
+
+*Example*:
+------------------------------
+popup_during_fullscreen ignore
+------------------------------
+
+=== Focus wrapping
+
+When being in a tabbed or stacked container, the first container will be
+focused when you use +focus down+ on the last container -- the focus wraps. If
+however there is another stacked/tabbed container in that direction, focus will
+be set on that container. This is the default behaviour so you can navigate to
+all your windows without having to use +focus parent+.
+
+If you want the focus to *always* wrap and you are aware of using +focus
+parent+ to switch to different containers, you can use the
++force_focus_wrapping+ configuration directive. After enabling it, the focus
+will always wrap.
+
+*Syntax*:
+-----------------------------
+force_focus_wrapping <yes|no>
+-----------------------------
+
+*Example*:
+------------------------
+force_focus_wrapping yes
+------------------------
