- * Detach or reattach \var{reg}, depending on whether \var{how}
- * is \codestr{set}, \codestr{unset} or \codestr{toggle}. (Detaching
- * means making \var{reg} managed by its nearest ancestor \type{WGroup},
- * framed if \var{reg} is not itself \type{WFrame}. Reattaching means
- * making it managed where it used to be managed, if a return-placeholder
- * exists.)
- * If \var{reg} is the `bottom' of some group, the whole group is
- * detached. If \var{reg} is a \type{WWindow}, it is put into a

+ * Detach or reattach \var{reg} or any group it is the leader of
+ * (see \fnref{WRegion.groupleader_of}), depending on whether \var{how}
+ * is \codestr{set}, \codestr{unset} or \codestr{toggle}. If this

+ * Detaching a region means having it managed by its nearest ancestor
+ * \type{WGroup}. Reattaching means having it managed where it used
+ * to be managed, if a ``return placeholder'' exists.
+ *
+ * Additionally, setting \var{how} to \codestr{forget}, can be used to
+ * clear this return placeholder of the group leader of \var{reg}.
